Migration issue with Flutter 3.0

This type error occures when I want to launch my app:

Warning: Operand of null-aware operation '!' has type 'WidgetsBinding' which excludes null.

• 'WidgetsBinding' is from 'package:flutter/src/widgets/binding.dart' ('../flutter/packages/flutter/lib/src/widgets/binding.dart').
  WidgetsBinding.instance!
