flutter - Flutter此函数的返回类型为 'Future'，但不以return语句结尾

Question

我正在使用此方法，并且收到此消息。我该如何纠正？

This function has a return type of 'Future', but doesn't end with a return statement. Try adding a return statement, or changing the return type to 'void'.

Future<bool> _onWillPop() {
Navigator.of(context).pop(false);
Navigator.pushNamed(context, '/home');}

return WillPopScope(
    onWillPop: _onWillPop,
    child: Scaffold

谢谢!

Answer 1

您必须从return的bool _onWillPop()

Future<bool> _onWillPop() { 

  Navigator.of(context).pop(false);
  Navigator.pushNamed(context, '/home');
  return true;// or false as per your need

}
