I am trying to automate, in flutter web integration_test, wherein I want to select multiple widgets by long pressing shift key and mouse drag. May I know if this is possible, if yes, then how? or if not possible, then is there any alternate way to achieve this selection?
For reference, I have attached an image to get more clarity if my objective.
To hold the shift you can try like this
await simulateKeyDownEvent(LogicalKeyboardKey.shiftLeft);
You can try creating a gesture then starting it based on location
final Offset firstLocation = tester.getCenter(find.byKey('keyName'));
final TestGesture gesture = await tester.startGesture(firstLocation, pointer: 5);
await tester.pump();
Then to drag you can use
final Offset secondLocation = tester.getCenter(find.byKey('Key2Name'));
await gesture.moveTo(secondLocation);
await tester.pump();
Then do gesuture.up
await gesture.up();
and to release shift you can do
await simulateKeyUpEvent(LogicalKeyboardKey.shiftLeft);
