For Flutter applications, we highly recommend exporting and uploading a debug build of your application to Waldo. This will allow Waldo to extract a more accurate view hierarchy for your tests. Learn more about debug builds in Flutter documentation.

Apart from that, there are no specific steps required in the build process, you can simply refer to the Xcode and Android Studio documentation:

Supported version

We support Flutter up to version 3.19 ("<= 3.19.x").
