The backgroundHandler needs to be either a static function or a top level function to be accessible as a Flutter entry point

here is error

actually I want navigate to second page after user select my notification in background mode but I got this problem

Answer 1

Put the definition of function used as backgroundHandler outside of any class.

For example:

// If in main.dart
main() {
  // ...
}

ClassABC {
  void getLetter() => print('a and b');
}

// Notice how this is outside of classABC scope and main scope.
backgroundHandler() {
  // Put handling code here.
}

For more clarity, could you post the whole page code?
