Added matrix builds to build across channels. (#601)

* Added matrix builds to build across channels.
* Added strict code quality checking to CI builds (must pass analyze and formatting).
* Skip redundant `package get` from Analyze step too.
* Removed version from example `pubspec.yaml` since it does not apply.
* Added `dry-run` switch to `flutter format` since we only need to detect formatting issue.
