I am new to Flutter. I have tried majority of data table structure but unable to create this functionality.
How to create similar table structure as shown in image with dynamic data?
You should take a look at this package: https://pub.dev/packages/data_table_2
It almost looks exactly like what you provided and I am sure you can customize it further.

Please Help to create this design with slider.
You can use a package like audio_waveforms in flutter.

I haven't tested it. Although it looks like it can do the job.
I am interested in how can I replicate the table that looks like on picture under "Known Media Players". I looked into .glade file of PulseAudio plugin and it seems like it was implemented using GtkTable which was deprecated in favour of GtkGrid. How can I replicate the table layout and the "header" of the table using GtkGrid?
I am trying to build my first own extension with the Extension Builder. Up to now everything worked really well, but now I've got a problem and am not able to find a solution:
My extension looks like this: You can add new Entries in the backend under List (the entry on the right panel). These entries are then shown in the frontend.
While adding new entries there is the possibility in the horizontal navigation bar to link this entry to specific categories. I've already done this with every entry.
But how can I display this category in the fronted. It should be just one <div> like Linked Categories: CATEGORY.
It seems like there is no ViewHelper which can display all linked categories.
I've already googled a lot, but this just confused me more: It seems like its not possible with a simple ViewHelper. There was a solution, where one had to edit the controller. But I did not like this because then I can not continue working with the Extension Builder or it becomes overwritten.
I also looked in the code of tx_news. It seems like all categories are in a variable there, which can be looped. But in my extension <f:debug>{categories} was always NULL.
Is there no ViewHelper which can display the categories, or anything else? Maybe a good tutorial (I am good in PHP, but new to TYPO3).
Thank you very much in advance,
Felix
P.S: I am using TYPO3 CMS 7.6.9
the Extension Builder is just a 'kickstarter' that helps you define your models and actions, relations etc ... It will not do more then that. So once you created your extension draft, it's best to forget about the extension builder and try to understand the structure of an extbase extension (the MVC, TCA, localconfig, typoscript,...). If you need to add a new property, do it manually. You will learn a lot more about your extension and how it works.
Having this said, you will have to adjust your extansion yourself to add categories. There are a few ways to do it: you can add your own category system by adding your own category Model, or use the TYPO3 category API
https://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/Categories/Index.html
There is also no plug&play category viewhelper. If you like to be able to list your entries by category, you will need to adjust your controller.
You can add some functionality to an existing on, for ex. your listAction so that it reads arguments send to this action (a list of categories you like to filter on) or create a new one called for example categoryAction.
extbase reference :

stackoverflow question about categories in a controller:
Controllers and Template (how to filter results correctly or give arguments via backend?)
bottom line:
- skip extension builder
- learn how to adjust the MVC yourself

In my project, I've got a list of countries from a database. In Ionic 2, the select option is alert (popup). I don't need that, so my question:
How can I create a custom picker for countries list?
I just build a similar component here, base on the low-level picker component.
https://github.com/raychenfj/ion-multi-picker
Chinese City Picker
But its performance could depend on your data volume.
Fengjun Chen thanks for designing the custom Picker control.
Can you post the source for the source for the Advance usage example that you hosted on - https://raychenfj.github.io/ion-multi-picker/
Also it will help if you can post an example of how to access the events and how to style the control.
I need a way of creating a table of data in landscape mode. This table should be in PDF form, is this possible on iPhone? If so please can someone advise on how to do it? If not, what are my other options?
I believe following link would definitely help you to create table using drawLine method in a loop. You can simply modify the drawLine method and implement to draw table for you. Also the code is very Handy to use with a very customizable methods for PDF creation.

For more help you can refer previous post.
create your table in UIWebView and then follow this link to make pdf from UIWebView
http://coderchrismills.wordpress.com/2011/06/25/making-a-pdf-from-a-uiwebview/
Easiest is using HTML. You can do all the text processing in objective-C and display the table in a simple UIWebView. This also gives you great control over how it is going to look.
