For this purpose, I will introduce you to the Flutter Example Widget test and after that, we will create our own widget tests in three different Test Scenarios.

For someone who has just started doing TDD, this was really helpful. I noticed you did a live stream with Flutter 1.22 live learning. Could I request a video idea? Maybe a video on the new Navigator 2., 0 API since I am having a hard time understanding it. Another great video would be a rundown of all you learnt in and since that live stream. I hope to see more videos and thank you for making the awesome content. <3

thank you for the video. I came here to find how to test if my scrollbar appear or is hidden because I extend the time it is shown and want to keep this behavior. Is it possible to find the scrollbar? I tried to find the ScrollbarPainter widget but doesnt work.
