Help Needed: Automation Test Failing with 'Unexpected Null Value' in FlutterFlow

Hi FlutterFlow Community,

I am facing an issue while running my automated tests in FlutterFlow. One of my test cases is failing with the following error:

Error Details:

csharp

Copy code

Test failed. See exception logs above. The test description was: Login with valid credentials. Failure Details: Failure in method: Login with valid credentials == EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK == The following TypeErrorImpl was thrown running a test: Unexpected null value. When the exception was thrown, this was the stack: dart-sdk/lib/internal/js_dev_runtime/private/ddc_runtime/errors.dart ...

What I Have Tried So Far:

1. Verified that all input fields in the form (email and password) are being filled correctly before submission.

2. Checked for any null values in the widget tree during the test using debugging tools.

3. Ensured that the app's state is properly initialized before the test begins.

Code Snippet: Here’s a snippet of the relevant test code:

dart

Copy code

void main() async { testWidgets('Login with valid credentials', (WidgetTester tester) async { await tester.pumpWidget(MyApp()); await tester.enterText(find.byKey(Key('email')), '[email protected]'); await tester.enterText(find.byKey(Key('password')), 'password123'); await tester.tap(find.byKey(Key('loginButton'))); await tester.pumpAndSettle(); expect(find.text('Welcome'), findsOneWidget); }); }

Environment Details:

• FlutterFlow Version: v5.0.0+ released December 18, 2024

• Flutter SDK Version: Flutter 3.24.5

• Testing Framework: Visual Studio Code

Questions:

1. Has anyone encountered this "Unexpected null value" error in their tests?

2. Are there any specific best practices to avoid such null-related issues during automation testing in FlutterFlow?

3. Could this error be related to state management or the way widgets are initialized in FlutterFlow?

Any insights or suggestions would be greatly appreciated!

Thank you in advance for your help! 😊
