如何处理 FirebaseAuthException？

Question

I coded self-defined function for checking email and password with using Firebase, as follows;

Future<bool> loginCheck(ref) async {
  // loadingStart();
  try {
    final FirebaseAuth auth = FirebaseAuth.instance;
    await auth.signInWithEmailAndPassword(
      email: loginIdController.text,
      password: loginPassController.text,
    );
    // loadingEnd();
    return Future<bool>.value(true);
  } on FirebaseAuthException catch (e) {
      // print(e.code);
      //Do something
    } else if (e.code == 'network-request-failed') {
      //Do something
    } else {
      //Do something
      // loadingEnd();
    return Future<bool>.value(false);
  }

However, under FirebaseAuthException catch (e){} always error occurs like screen shot below.

I'm sorry that I'm very new about not only flutter/firebase but vscode, and could not detect the reason why I cannot catch the error appropriately.

Could someone advise me why this happen? thanks for your kindness.

The issue is that you have a breakpoint. See the red circle on the side of the line the code crashed at. Click it to remove it. They are used for debugging and checking the flow of your code

Also in the bottom left of the second screenshot you can see the breakpoint again and the options for catching breakpoints and errors. Learn these too
