Ever since Flutter had its first stable version released, it has been growing rapidly among us mobile developers. Today, flutter is the default choice for many of us. However, the framework is still relatively new, and there are some aspects in which it is not very mature yet. Until December 2020, the framework didn't have a good solution for integration testing. Developers that wanted to go down this road needed to use flutter driver tests, which was not a robust tool and would not be enough to fully test a complex app, in my point of view.
