Get ready to unlock the potential of Flutter and Dart as you learn to craft visually stunning and high-performance applications for both Android and iOS.

This course will teach you to plan, build, and deploy interactive Flutter applications. You’ll start by developing user interfaces and handling gestures. Next, you’ll explore navigation and routing to smoothly move around your app. You’ll then dive into networking and HTTP to connect your app to the internet and implement data persistence. You’ll use Firebase services for authentication and storing data. State management comes next, helping you manage the different pieces of your app efficiently. Then, you’ll focus on testing, analytics, and crash reporting. You’ll then explore accessibility and internationalization, making your app usable by everyone and suitable for different languages. Lastly, you’ll learn app deployment.

The course wraps up with a project: you will create an online furniture store, combining all the skills you’ve learned.

The Complete Guide to Flutter

# Challenge solutions

Great job on completing all the steps in the previous challenge! Feel free to compare your code solutions with the solutions below:

## Solution 1: Test if the tasks are visible

1. Pump the `TasksList` widget in readiness for testing.

    ```Dart
        // Build the widget to test
        await tester.pumpWidget(
            MaterialApp(home: Scaffold(body: tasksListWidget)),
        );
    ```

2. Use finder functions to confirm that tasks are shown on screen.

    ```Dart
        // Verify that tasks are shown
        expect(find.text('Task 1'), findsOneWidget);
        expect(find.text('Task 2'), findsOneWidget);
        expect(find.text('Task 3'), findsOneWidget);
    ```

## Solution 2: Test if the tasks can be dismissed

1. Drag a task to dismiss it from the screen.

    ```Dart
        // Drag the task to dismiss it
        await tester.drag(
          find.ancestor(
            of: find.text('Task 2'),
            matching: find.byWidgetPredicate((w) => w is CheckboxListTile),
          ),
          const Offset(500, 0),
        );
    ```

2. Wait till the drag to dismiss action is completed.

    ```Dart
        // Wait for the task to be dismissed and delete confirmation SnackBar shown
        await tester.pumpAndSettle();
    ```

3. Test that the task has been removed from the screen and a `SnackBar` has been shown to the user, confirming that the task is deleted.

    ```Dart
        // Verify that the task is deleted and a SnackBar is shown
        expect(find.text('Task 2'), findsNothing);
        final snackBarFinder = find.byType(SnackBar);
        expect(snackBarFinder, findsOneWidget);
    ```
