Is there any possibility to show the source code of flutter objects? - flutter

I do have a question. I´m programming and I wonder, if there is any possibility to show the standart setting of widgets (Container etc.) or other things.
I looking forward to hear from one of you. :)

If you want to find out the source code of an object, then
Ctrl + (click on the object)
Use ctrl + space for more info

To see the source code in flutter Ctrl and click on the object in windows and if you are on Mac then click Command Button and then click on the object and it should show you the source code for the object

Hide other windows (CMD + Option + H) shortcut for VS Code on macOS

In proper mac applications you can use command+option+H to hide all apps except the currently active program. This does not work in VS Code for some reason. Is there a way to get this functionality?
You could try this I found setting each app individually worked for me.
Senario
I wanted to prevent vscode from using Hide Visual Studio Code which, by default was mapped onto cmd+H keyboard shortcut. I changed it to the way illustrated in the screegrab and it worked. Perhaps you could do the same?
Edit
I actually attemped it and it worked with the same combo you wanted. See the screen grab below:
Happy coding =)

Method List in Visual Studio Code

I've recently started using the Visual Studio Code editor. I'm really loving it, but there's one critical feature (for me) that I haven't been able to find. Is there a method list, similar to the Navigator in NetBeans or Member dropdown in Visual Studio?
Yes, there is the workbench.action.gotoSymbol command. On Windows and Linux it's set to CTRL+Shift+O by default, on Mac it's Cmd+Shift+O.
If this command isn't available for the file types you are working with then you should take a look at the VSCode extensions. Not all languages support this feature.
Update: As stated in the comments by #jeff-xiao this extension is Deprecated and it's now a built in feature of Visual Studio code. It should be available at the bottom of file explorer as "Outline" view.
Previous text:
There is now an Extension that supports this. Code Outline creates a panel in the "Explorer" section and for JavaScript, will list variables and functions in a file. I've been using this for a while now and it scratches the itch I had. Other commenters have mentioned it supports Python and PHP well.
It still seems to be in development but I haven't had any issues. Development version available on GitHub. If you're the author reading this - thanks!
This is how it looks:
If Code Outline is not visible, you can show it by:
Invoke Code's Go to symbol command:
macOS: cmd+shift+o (the letter o, not zero)
Windows/Linux: ctrl+shift+o
Typing a colon (:) after invoking Go to symbol will group symbols by type (classes, interfaces, methods, properties, variables). Then just scroll to the methods section.
In 2020 version of VSCode
Cmd+P
# - Find symbol across files
# - Find symbol within file
#: - Group symbols within a file
In VSCode 1.24 you can do that.
Right click on EXPLORER on the side bar and checked Outline.
There is a new release that can do that!
Check here the latest release notes regarding code outline
UPDATE: The extension features are now built-in and the extension itself is now deprecated
I have found this extention: Code Outline.
This is how it looks like:
I believe that is what you have been looking for.
There's no such feature today,
the CTRL+SHIFT+O == CTRL+P # doesn't work for all languages.
As a last resort you can use the search panel - although it is not so fast an easy to use as you'd like - you can enter this regex in the search panel to find all functions:
function\s([_A-Za-z0-9]+)\s*\(
For PHP users :)
Make sure you have 'PHP Symbol' plugin then you can get all methods and class in 'OUTLINE' Sidebar's Bottom.
Press ⌘ command + ⇧ shift + O in "macOS" or Ctrl + Shift + O while using "Windows"
OUTLINE:
#Symbol:
For python in Explorer View, click on OUTLINE as below:
Visual Studio Code market place has a very nice extension named Go To Method for navigating only methods in a code file.
Hit Ctrl+Shift+P and type the install extensions and press enter
Now type Add to method in search box of extensions market place and press enter.
Click install to install the extension.
Last step is to bind a keyboard shortcut to the command workbench.action.gotoMethod to make it a real productivity thing for a developer.
Watch this link: https://code.visualstudio.com/updates/v1_40#_type-filters-for-outline-and-breadcrumbs
Explorer -> OUTLINE, you can choose what you want to show (only methods and functions in your case) and the result is similar to Netbeans:
Open symbol by name :
CTRL+T
might be what you are looking for. Works perfectly with my TypeScript project.
It is an extra part to the answer to this question here but I thought it might be useful. As many people mentioned, Visual Studio Code has the OUTLINE part which provides the ability to browse to different function and show them on the side.
I also wanted to add that if you check the follow cursor mark, it highlights that function name in the OUTLINE view, which is very helpful in browsing and seeing which function you are in.
ctrl+shift+o // This should work for javascript files by default
For PHP install the extension PHP SYMBOLS
FOR PYTHON install the extension PYTHON
On Reload, this will work fine
in-built code OUTLINE available now with VS code
There is a plugin called show functions which lists all the function definitions in a file. It also allows you to sort the function so can search them easily.
CTRL+F12 (CMD+F12 for Mac) - opens for me all methods and members in PHP class.
For find method in all files you can press CTRL + P and then start search with #
example : #signin
Take a look at Show Functions plugin.
It can list functions, symbols, bookmarks by configurable regular expressions. Regular expressions are a real saver, expecially when you're not using a mainstream language and when CodeOutline doesn't do the job.
It's ugly to see a split window with these functions (CodeOutline seems to be better integrated) but at least there's something to use
If you are using typescript you can use this extension "Code navigator for typescript".
I have been trying it and found it useful to list my typescript class methods.

SQLDeveloper jump between Package body and Package spec

I'm currently using Oracle SQLDeveloper a lot more that I have ever used and I'm starting to like the tool.
I use Shift+F4 a lot to jump into a package/function/procedure. But one thing that I don't really get is how to jump directly to the package body or as an alternative some kind of shortcut that toggles between the spec and the body of a package.
Toad has something like this and I'm unable to find this feature in SQLDeveloper.
I'm also aware that you have the object tree on the left side of the screen but it's not really the best way to navigate to a package body when you are already looking at its specification. Especially if you have something like 300 packages with similar names...
For someone that uses SQLDeveloper to work everyday and does a lot of development with packages there has to be a way to do this...
I'm hoping for some magical shortcut or some obscure plugin.
see the picture above-- the downward pointing side arrow -- click on it-- it will open up the function defintion.
thanks
After opening the package spec using Shift+F4, press Ctrl+Shift+F12 to open or toggle between body and spec
Go to VIEW menu, click on find DB objects option. In the find db object pane put the name of the package and select the DB.
Both, the spec and body will appear, double click to open.
You have a couple of questions:
how to 'jump into' a pl/sql object AND
how to toggle from spec to body and vice versa
How to 'jump into' a pl/sql object
Ctrl+Mouse Hover+Click
If you don't like this mouse-kung-fu, you can also assign a keyboard shortcut, I show you how to do this here.
How to toggle from spec to body and back
You can use the arrows in the gutter, they point up or down, you can use the toolbar button, or you can use the keyboard shortcut.
If you use the 'arrow' in the gutter, you'll go straight to that item's corresponding bit in the spec or body. Using the toolbar button/kb shortcut will just take you to line 1 of the spec or body.
I talk about these PL/SQL features and more on my blog.
(this is at least with my PLSQL-DEv version (11.0.4.1774), default settings)
The shortcut to view Spec. + Body is SHIFT+ F5, then CTRL+ H to toggle to the "body" tab.
This works if you have certain rights to view the package's body, especially the DEBUG right: ask your DBA to do you a
GRANT DEBUG on <package_you_want_to_view_the_body_of> to <your_user>
or
GRANT DEBUG on <package_you_want_to_view_the_body_of> to PUBLIC
Note sure but you might also need the EXECUTE right just to view. Same thing if needed, ask your DBA similar above grant.
nb:
Another thing I had to do in Oracle 12c for Code assistant to view the packages when typing: check the "Use DBA Views if available" in Tools > preferences:

What are the must know shortcuts in Xcode for faster application development?

What are the must know shortcuts in Xcode for faster application development?
As a special interest, the Mac shortcut I want to know is the one to open application menus (File, Edit, View, Project, Build etc.,). In Windows, if we type Alt + F, the File menu will drop down, and we can navigate through the sub-menus using the arrow keys or typing the letters that are underlined in the menus. How can we do something like that in Mac?
Thanks..
For debugging:
CMD+SHIFT+I (step into)
CMD+SHIFT+O (step)
Building & Running:
CMD+B (build project)
OPT+CMD+ENTER (debug project)
This is the PDF for all the shortcuts of Xcode
All Xcode Shorcuts
I hope it helps.
Alt + Cmd + Up to toggle between .h and .m files of a class
Cmd + ' to move to next error or warning
Cmd + Shift + ' to move to previous error or warning
Column Selection: Holding down the option key while dragging allows you to perform a column based selection of text. Might be useful in limited circumstances.
Control-. to select the next autocompletion, control-/ to select the next placeholder (add shift for previous), control-escape to show autocompletion list.
As a response to your request, if you have full keyboard access turned on, control-fn-F2 will select the menu bar. Then use the arrows to select an item, and space to choose it.
These shortcuts are for Xcode 3.2.x (they may vary from Xcode 3.1.x and other versions):
Command-double click on symbol/method name in source code editor > Open the .h file for symbol
Option-double click on symbol/method name in source code editor > Open the documentation for symbol
Command-Option-Shift-F > Find Selected Text in Project (custom shortcut)
I have the following one setup in User Scripts under Code to insert a standard logging call:
The inserted text is:
NSLog(#"[%# %#]", NSStringFromClass([self class]), NSStringFromSelector(_cmd));
Shift-Command-D (Xcode 3.2) / Shift-Command-O (Xcode 4): Open quickly. Great way to get to the file you want.
"Alt + Cmd + Up to toggle between .h and .m files of a class"
This seems to have been disabled in Xcode 4. I've not been able to find a way to set it in Bindings, either. Any hints?
Update: Just found it. It has been changed to "Ctrl + Cmd + Up". It can also be executed with a three finger swipe up or down.
The command, by the way, is called "Jump to Next Counterpart". I knew that.... :-/
Sometimes it takes a Ph.D. in linguistics to figure computer terminology out. And I've been doing this since the early 80s.
Click on any method name in the Xcode.
Then use ALT + CMD + / to insert comments describing the input and return parameters.
This will encourage you to write descriptive comments explaining what is the method supposed to do, thus leading to a more maintainable code.
Use CMD + SHIFT + O to open the Open Quickly Dialog. While you type classes, methods and files will appear matching your entered description. Pressing enter will go to said method, class or file. This greatly improved productivity for me.

How do I jump to a method in RubyMine?

In Visual Studio, the editor has a drop-down list of functions in the current class; clicking on one will take me to the top of that function. Is there a way to get a similar behaviour from RubyMine?
I suggested this as a feature request to the folks at JetBrains, and within the day they got back to me to tell me about the 'File Structure Popup' on ^F12 which does very nearly what I want; it's an extra keypress but I can live with it.
If you're working on a Rails project, change the project view to Rails (change the View as: dropdown value)
Online help is here.
It looks like this is as close as it gets to the functionality you're looking for.
Ctrl+0 key in editor will show all methods with search capacity.
The same is drop-down menu Navigate -> File structure.
