Flutter auto importing extension file is not working - flutter

I have a simple String-Extension which looks like this:
extension TranslationHelper on String {
String localized() {
return AppLocalizations(Locale('de', 'DE')).translate(this);
}
}
With this I am able to call .localized() on any String.
Problem: Flutter or VSCode is not auto-importing the file for me and also not suggesting it with a Quick-Fix. Importing the file manually is quite painful. Is this a bug or what am I missing here?
All other importing works perfectly fine...

This is a known issue, and is being tracked.
As a workaround, typing the name of the extension should let you auto import it.
For example, with the following extension, typing MyExtension should allow you to import it.
extension MyExtension on Object {
void doSomething() {}
}

How to exclude UnityEditor reference from asmdef?

How to exclude UnityEditor reference from asmdef?
Why I need it:
I have an asmdef file. For example, it is MyAssembly/MyAssembly.asmdef. The MyAssembly contains a lot of features and each feature staff is placed in its own folder. And some of these features has a code that is needed only in editor, and it refers to UnityEditor namespace. Such editor code is placed into an Editor folder.
But as you know, Editor folder name means nothing in terms of asmdef usage. So I add AssemblyDefenitionReference in each folder and refer it to the MyAssemblyEditor.asmdef assembly definition. So the paths looks like this:
MyAssembly/MyAssembly.asmdef
MyAssembly/Editor/MyAssemblyEditor.asmdef - this folder contains no code. It's needed just to place asmdef, because it's not allowed to place two asmdefs in a single folder.
MyAssembly/SomeFeature/Editor/*feature editor staff*
MyAssembly/SomeFeature/Editor/Editor.asmref - refers to MyAssemblyEditor.asmdef
MyAssembly/SomeFeature/*feature staff*
All this works good. But the problem is that, when some developer adds a new feature, he can forget to add a reference to the MyAssemblyEditor.asmdef in the editor folder. And there are no any errors will be shown in this case. This mistake will be revealed only when the build will be cooked. But I'd like that using of UnityEditor in MyAssembly will be instantly marked as an error.
Feel free to suggest other solution for this problem.
This thread got me thinking I can use CsprojPostprocessor to remove all references to UnityEditor from my csproj file. I wrote such class:
using System.Text.RegularExpressions;
using UnityEditor;
// ReSharper disable once CheckNamespace
public class CsprojPostprocessor : AssetPostprocessor
{
public static string OnGeneratedCSProject(string path, string content)
{
if (!path.EndsWith("Editor.csproj") && !path.EndsWith("Tests.csproj"))
{
var newContent =
Regex.Replace(content, "<Reference Include=\"UnityEditor(.|\n)*?</Reference>", "");
return newContent;
}
return content;
}
}
It also can be done with an xml parser or something.
The only thing, that confuse me is that this mechanism is badly documented and doesn't look like something simple users should use. So I use it at my own risk, but looks like there is no guarantee it will be strongly supported in future.

How to get vscode intellisense to work without importing header files in C++?

I am solving leetcode problems in vscode and I am having problems with the autocomplete/intllisense as the solutions are required to implement only a function( example below).
class Solution {
public: int removeDuplicates(vector<int> &nums) {
//write the solution here
} };
So autocomplete is not working as there is no import statement for the header files ( like #include<...>). So how can I use the intellisense in this case.

Go to definition, go to implementation, autogenerate import for Ember

Im using Ember with VS Code.
What I need is to generate import string on a fly when I encounter dependency. For example I write someting like:
#tracked isLarge = false;
But I don’t have “#tracked” imported yet. So the otion could be to set the coursor on #tracked, press something like “Action + .” and pick “generate import”. It should generate import string:
import { tracked } from '#ember/tracking';
But it doesn’t work out of the box. How can I do that?
UPDATE: the same question about:
go to definition
go to implementation
cmd+click to navigate to implementation/component
You can use the extension My Code Actions
You can create actions that just insert the text independent of an error.
"my-code-actions.actions": {
"[javascript]": {
"import tracked": {
"where": "insertAfter",
"insertFind": "^import",
"text": "import { tracked } from '#ember/tracking';\n"
}
}
}
The key combo to use is the Code Action combo: Ctrl+.
If you get a diagnostic (PROBLEM panel, and squiggle) you can use that to further customize the action and you can use text from the diagnostics message.
I'm current adding the possibility to make multiple edits in an action and to use further customization and generalization.
"Ember Language Server" brings some solution. But it works mostly with library code that has .d.ts typings.
In case of custom JS code it still doesn't work.
So there is no straight solution. Only 2 ways:
Write .d.ts typing for custom code JS files
Move project to typescript

How to type hint class definition

Consider the following example of 3 javascript files:
/** myclass.js **/
import jQuery from 'jQuery';
class MyClass {
constructor() {
this.property = null;
jQuery('#test').data('myClass', this);
}
testMethod() {
return null;
}
}
export default MyClass;
/** file.js **/
import MyClass from './myclass.js';
new MyClass();
export default null;
/** index.js **/
import './file.js';
import jQuery from 'jQuery';
let myValue = jQuery('#test').data('myClass');
What I would like to achieve, is to get property and method auto suggestion from my IDE on the myValue variable. I know (I mean I presume) that automatically, there is no way for the IDE to know what I stored in the data variable of jQuery, but what kind of type hint should I provide before myValue to tell the IDE, that it should be an instance of MyClass?
If in index.js I also import myclass.js with the definition of the class, I was able to achieve my result, by type hinting before the variable with the following jsdoc comment:
/** #type {MyClass} */
But this line only works if I also imported the definition in the current scope. Is there any way to either:
achieve suggestions automatically, without manually type hinting?
or if that is not possible, type hint, without manually importing the definition beforehand?
I am using Visual Studio Code v1.46.1 and I have the ESLint v2.1.5 extension installed on it.
EDIT: After trying to create a jsconfig.json file in my root folder, with the following options:
{
"exclude": ["node_modules"]
}
and modifying my index.js by adding this jsdoc comment, I am still getting no autosuggestions by VSCode:
/** #type {MyClass} */
I've tried adding the above comment both above, and below the line, where I fetch the data from the jQuery element.
EDIT 2:
Okay, basically, it looks like that my IntelliSense "breaks" when I am trying to export something from a file. Could this be a VSCode issue?

typescript can't resolve non-relative path in import

I have project structure like this
|--src
|--app.component
|--index.ts
|--home.component
|--index.ts
|--tsconfig.json
|--webpack.config.js
And I'm trying to do stuff below in app.component-index.ts
import { HomeComponent } from 'components/home.component'
Typescript couldn't find this module and throws
error TS2307: Cannot find module 'home.component'
Typescript docs say next:
A non-relative import to moduleB such as import { b } from "moduleB",
in a source file /root/src/folder/A.ts, would result in attempting the
following locations for locating "moduleB":
/root/src/folder/moduleB.ts
/root/src/moduleB.ts
/root/moduleB.ts
/moduleB.ts
So for my case I expect it would be like
/src/components/app.component/components/home.component
/src/components/components/home.component
/src/components/home.component
Thanks in advance.
P.S. In my webpack.config I've setted root.resolve to src and everything bundles correct. Typescript-loader prints errors to terminal but everything is bundled and works correctly
So I can guess at the "why" portion of this but I'm relatively new to TypeScript. I have gotten this to work though so I'll try explaining based on that solution as best I can.
What you expect based on the TypeScript Docs would be mostly correct if:
'components/home.component'
were treated as a 'Non-relative import'. I'm fairly certain (based on the solution that worked for me) that TypeScript treats it as an absolute path from the 'compilerOptions.baseUrl' field in your tsconfig.json.
What worked for me was to set it like so:
{
"compilerOptions": {
"baseUrl": ".",
// Other options
}
}
Which essentially tells TypeScript to try and find something like
'components/home.component'
by looking in the same directory as the tsconfig.json file for a directory called 'components' and then to look for a file/directory within it called 'home.component'.
So if your structure looks like:
|--src
|--app.component
|--index.ts
|--home.component
|--index.ts
|--tsconfig.json
|--webpack.config.js
And you set baseUrl to "." you would probably need to format your import like
import { HomeComponent } from 'src/home.component'
