error running tests on latest packages

[cklanac]

Received the following error when running tests on the latest packages.

Test: "WHEN user enters a valid email and passwordAND user taps on the sign-in buttonTHEN
signInWithEmailAndPassword is calledAND user is signed in"

══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞════════════════════════════════════════════════════
The following assertion was thrown running a test:
Tried to listen to a value exposed with provider, from outside of the widget tree.

This is likely caused by an event handler (like a button's onPressed) that called
Provider.of without passing `listen: false`.

To fix, write:
Provider.of<AuthBase>(context, listen: false);

It is unsupported because may pointlessly rebuild the widget associated to the
event handler, when the widget tree doesn't care about the value.

The context used was: EmailSignInFormStateful(dirty, state: _EmailSignInFormStatefulState#4ce1f)
'package:provider/src/provider.dart':
Failed assertion: line 202 pos 7: 'context.owner.debugBuilding ||
          listen == false ||

The test description was:
  WHEN user enters a valid email and passwordAND user taps on the sign-in buttonTHEN
  signInWithEmailAndPassword is calledAND user is signed in

[cklanac]

Fixed by adding listen: false to the _submit method. Fixed in PR #3

Future<void> _submit() async {
    setState(() {
      _submitted = true;
      _isLoading = true;
    });
    try {
      final auth = Provider.of<AuthBase>(context, listen: false);
      if (_formType == EmailSignInFormType.signIn) {
        await auth.signInWithEmailAndPassword(_email, _password);
      } else {
        await auth.createUserWithEmailAndPassword(_email, _password);
      }
      if (widget.onSignedIn != null) {
        widget.onSignedIn();
      }
    } on PlatformException catch (e) {
      PlatformExceptionAlertDialog(
        title: 'Sign in failed',
        exception: e,
      ).show(context);
    } finally {
      setState(() {
        _isLoading = false;
      });
    }
  }
