Been away from flutter community for almost a year. What's new?
Specifically, whats the preferred state management these days? I extensively used redux for a while but is it still relevant? Are there better ways to do state-management now? what are other recent changes I should be aware of?thanks :)

Execute code in x duration while app in background but not terminated
I have an app that has a timer and after it reaches <5 seconds, it will notify user that it's almost time and at the same time run some code.​However when I lock my phone, it seems the timer is stopped as well, hence no code execution.​How do I run some code in x seconds as specified by user while the app is still in the background (aka tap on home button the app goes to background but not terminated.). If the app task is ended i do not care as I won't be bothering the user.​Is this possible?

A suggestion from the community
Hey,I need some suggestions regarding the course that i would like to deign. I intend it to be the best course when looking out for a complete app experience in flutter(from UI design to backend ,API and Publishing). I would like the following suggestions:Which back-end and hosting platform to use? Either a custom back-end or AWS or vanilla GCP or even server less Firebase kind?API using Flask(I'm most comfortable with that) vs deno/any other JS framework vs PHPState management? Bloc or Provider?local persistence in SQFLite or Hive or normal Shared Preferences?Should i include principles of TDD as well?Should i also discuss evaluating the price for your product while working as a freelancer in the same series ?Also, should i encourage people to use the libraries provided by GCP etc for ML or should i encourage them to make their own and use it since they must be more flexible in the long run and dependency is removed from third parties for your product?Would appreciate it a lot for the suggestions.Thank you in advance.

Change state of GridView from another file
Hello guys,I have this simple GridView which is in sellBook.dart:

Widget _takePicture() { return Container( margin: EdgeInsets.symmetric(vertical: 10), width: AppTheme.fullWidth(context), height: AppTheme.fullWidth(context) * 0.5, child: Container( alignment: Alignment.center, child: GridView( gridDelegate: SliverGridDelegateWithFixedCrossAxisCount( crossAxisCount: 1, childAspectRatio: 1, mainAxisSpacing: 5, crossAxisSpacing: 10), padding: EdgeInsets.all(10), scrollDirection: Axis.horizontal, children: AppData.sellImages .map((product) => sellImageCard( product: product, )) .toList()), ) ); } 

This gridview lists sellImageCard which are cards defined in an other file:

 void _settingModalBottomSheet(context){ showModalBottomSheet( context: context, builder: (BuildContext bc){ return Container( child: new Wrap( children: <Widget>[ new ListTile( leading: new Icon(Icons.camera_alt), title: new Text('Camera'), onTap: () => { getImage(), AppData.picture_count++, AppData.sellImages.add(new sellImage(AppData.picture_count, Image.asset('assets/camera.png'))), print(AppData.sellImages[AppData.picture_count].id), } ), new ListTile( leading: new Icon(Icons.camera), title: new Text('Gallery'), onTap: () => {}, ), ], ), ); } ); } } 

AS you can see when I click on a sellImageCard, I create a new card that I add to sellImages. But the gridView in sellBook doesn't update once a new card has been created. How could I update it? I guess I have to use setState but how can I access the state of a widget in an other file?Best regards
