Answer 1

first, you check AndroidManifest.xml (AndroidManifest.xml file for debug mode is different from AndroidManifest.xml file for release mode. check directory:

android\app\src\debug\AndroidManifest.xml

and directory:

android\app\src\main\AndroidManifest.xml

even you can create for release:

android\app\src\release\AndroidManifest.xml

try with add

to your target AndroidManifest.xml).

red screen in debug mode it's like grey screen in release mod that means you have an error code but for debug mode maybe this error be like warning and could run and you don't see any problem in your app in debug mode! but for release mode, you should fix it! like the case for me: I'm trying put Position Widget in Container Widget and I get this error :

Another exception was thrown: Instance of ‘DiagnosticsProperty’
Incorrect use of ParentDataWidget.

i fix it by change Container to Stack.
