Check out our Usage Guide

---

Easy keyboard shortcuts

flutter_test_robots adds methods to WidgetTester for many common keyboard shortcuts.

void main() {
  testWidgets("easy shortcuts", (tester) async {
    await tester.pressEnter();

    await tester.pressShiftEnter();
    
    await tester.pressAltLeftArrow();
  });
}

Simulate hardware keyboard text input

flutter_test_robots presses key combos for every character in a given string.

void main() {
  testWidgets("type with a hardware keyboard", (tester) async {
    // Simulate every key press that's needed to type "Hello, world!".
    await tester.typeKeyboardText("Hello, world!");
  });
}

Simulate IME text input

flutter_test_robots breaks strings into text editing deltas and sends the deltas through the standard DeltaTextInputClient API.

void main() {
  testWidgets("type with the IME", (tester) async {
    // Simulate every IME delta needed to type "Hello, world!".
    await tester.ime.typeText("Hello, world!");
  });
}

Simulate popular mobile devices

flutter_test_robots can configure a WidgetTester viewport like popular recent phones.

void main() {
  testWidgets("renders on iPhone 16 Pro Max", (tester) async {
    tester.asIPhone16ProMax();

    await tester.pumpWidget(MyApp());
  });

  testWidgets("renders on every built-in test device", (tester) async {
    for (final device in TestDevices.all) {
      tester.configureForDevice(device);

      await tester.pumpWidget(MyApp());
    }
  });
}
