tester.scrollUntilVisible() not working with GridView in flutter integration testing

I am trying to scroll and find widget from the GridView in integration testing in flutter. But the code not working:

tester.scrollUntilVisible(itemFinder, -100, scrollable: gridViewFinder)

But this is not working. It is saying GridView is not scrollable.

Solution

  • There are few steps I made mistake here:

    1. scrollUntilVisible() is Future, so

      await tester.scrollUntilVisible(...);

    2. to scroll down, delta should be positive:

      await tester.scrollUntilVisible(itemFinder, 100.0, ...);

    3. if there is only one list in screen, I don't have to include scrollable:

      await tester.scrollUntilVisible(itemFinder, 100.0);

    Now done! Final answer:

     await tester.scrollUntilVisible(itemFinder, 100.0);
