WidgetTester.sendKeyEvent(LogicalKeyboardKey.enter) does not trigger TextField.onSubmitted #116752
Description
Steps to Reproduce
- Execute the first test below under code sample, and observe that it fails
- Execute the second test below under code sample, and observe that it passes
Expected results:
WidgetTester.sendKeyEvent(LogicalKeyboardKey.enter) would call the onSubmit callback in a TextField
Actual results:
WidgetTester.sendKeyEvent(LogicalKeyboardKey.enter) can interact with buttons, but not form fields.
Code sample
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:flutter_test/flutter_test.dart';
void main() {
testWidgets('Can submit form field via LogicalKeyboardKey', (tester) async {
bool wasSubmitted = false;
final app = MaterialApp(
home: Material(
child: Center(
child: TextField(
onSubmitted: ((value) => wasSubmitted = true),
),
),
),
);
await tester.pumpWidget(app);
// Set initial focus to window.
await tester.tapAt(const Offset(0, 0));
// Move focus to first focusable widget via keyboard (TextField).
await tester.sendKeyEvent(LogicalKeyboardKey.tab);
// Press enter to submit
await tester.sendKeyEvent(LogicalKeyboardKey.enter);
expect(wasSubmitted, true); // <- THIS FAILS
});
testWidgets('Can submit button via LogicalKeyboardKey', (tester) async {
bool wasSubmitted = false;
final app = MaterialApp(
home: Material(
child: Center(
child: ElevatedButton(
onPressed: (() => wasSubmitted = true),
child: const Text('Submit'),
),
),
),
);
await tester.pumpWidget(app);
// Set initial focus to window.
await tester.tapAt(const Offset(0, 0));
// Move focus to first focusable widget via keyboard (ElevatedButton).
await tester.sendKeyEvent(LogicalKeyboardKey.tab);
// Press enter to submit
await tester.sendKeyEvent(LogicalKeyboardKey.enter);
expect(wasSubmitted, true); // <- THIS PASSES
});
