Migrating from WillPopScope to PopScope

Code before migration:

WillPopScope(
  onWillPop: () async {
    _myHandleOnPopMethod();
    return true;
  },
  child: ...
),

Code after migration:

PopScope(
  canPop: true,
  onPopInvoked: (bool didPop) {
    _myHandleOnPopMethod();
  },
  child: ...
),

Example: 
PopScope(
      canPop: false,
      onPopInvoked:(bool didPop) async{
        if (didPop){return;}
        controller.onPopScope();
   },
)
