How can I remove the debug banner in Flutter?

I am using flutter screenshot and I would like the screenshot not to have a banner. Now it does have.

Note that I get not supported for emulator message for profile and release mode.

Solution

On your MaterialApp set debugShowCheckedModeBanner to false.

MaterialApp(
  debugShowCheckedModeBanner: false,
)

The debug banner will also automatically be removed on release build.
