Theme Toggler Drawer in Flutter

[irahulcse]

The link of the dart pad is https://dartpad.dev/9abeece87fbd65cf36cf50084b91f5fc In this, I had implemented a drawer to toggle between dark theme and light theme in Flutter.

@divyanshub024 Pls, have a look at it.

Hey @irahulcse!! Thanks for your contribution but I cannot add this sample as setstate is not the right way to change theme dynamically which will reflect a whole app.

Hi, @divyanshub024 I had updated the Dartpad.dev code. And it's working fine without the setState method. The link of the pad is https://dartpad.dev/4ffc9c4a0520ecb48e7c35a7983a7df3. Pls, have a look at it.

@irahulcse There is 1 issue. check the logs.

Close instances of `dart.core.Sink` - line 53

Yes, This also bothered me. I am trying to solve it by reading different issues. But, till now it seems fine, Is this some kind of warning?
I am right now referring to the following:

1. Close instances of dart.core.sink doesn't recognize close in cascade dart-lang/sdk#57403
2. Close instances of dart.core.sink doesn't recognize close when using this dart-lang/sdk#57910

Referred this article for the syntax: https://medium.com/flutter-community/flutter-bloc-with-streams-6ed8d0a63bb8
In one of the issues, I had also read that if you moved to the analysis_options.yaml file present in the Flutter directory. In this also, very mentioned about the close.sinks.
Attaching the SC of that file:
