Integration tests

These tests are not hermetic, and use actual Flutter SDK. While they don't require actual devices, they run flutter_tester to test Dart VM and Flutter integration.

Some of these tests change the current directory for the process, so only one test can be run at a time. Use this command to run:

../../bin/cache/dart-sdk/bin/pub run test -j1
