You need to make your method Asynchronous

you can use futures, async, await

Try this way

Make your first method async method like below example

Future<int> methodOne() async {
    debugPrint('first method called');
    sleep(const Duration(seconds: 3));
    return 4;

  }
  methodTwo() {
    debugPrint('second method called');
  }

now you can call your methods like this

          GestureDetector(
              onTap: () async {
                await methodOne().then((value) {
                  methodTwo();
                });
              },
              child: Center(child: Padding(
                padding: const EdgeInsets.all(20.0),
                child: Text("Click Me"),
              ))),
