Solving nullabe function-CodePudding

I have this function and flutter have a problem becouse go to be null

 Widget getPicker() {
    if (Platform.isIOS) {
      return iOSPicker();
    } else if (Platform.isAndroid) {
      return androidDropdown();
    }
  }

I try to make it async

Future<Widget> getPicker() async {
    if (Platform.isIOS) {
      return iOSPicker();
    } else if (Platform.isAndroid) {
      return androidDropdown();
    }
  }

But problem still here. How i can solve it?

CodePudding user response：

Try tweaking your if statement this way :

 Widget getPicker() {
    if (Platform.isIOS) {
      return iOSPicker();
    }
    return androidDropdown();
  }

You can also use ternary operator:

 Widget getPicker() {
    return Platform.isIOS ? iOSPicker() : androidDropdown();
  }
