## Description This PR adds the 'Share' button to the text selection toolbar on Android. ## Related Issue Fixes https://github.com/flutter/flutter/issues/138728 ## Tests Refactor a lot of existing tests in order to: - make them more readable (avoid duplication by introducing helper functions, specify explictly check which buttons are expected). - make them more accurate (check that expected buttons are visible instead of just checking the number of buttons). For instance, previous tests contained sections such as: ```dart // Collapsed toolbar shows 3 buttons. expect( find.byType(CupertinoButton), isContextMenuProvidedByPlatform ? findsNothing : isTargetPlatformIOS ? findsNWidgets(6) : findsNWidgets(3) ); ``` Where the comment is obsolete, the two cases (6 widgets and 3 widgets) are not explicit (which buttons are expected?), and not accurate (will pass if the number of buttons is right but the buttons are the wrong ones).
