CI setup #27

This issue will track all changes made to the repository in order to take advantage of github actions and know if a PR could be merged without breaking something:

• Add action to run build for iOS, android ci(Build action): run a build for every PR #24
• Add action to run tests:
  • Flutter tests feat(pipeline):Created dart.yml #10
  • Android plugin implementation tests ci(android): run native android tests #18 and [CI] Run unit tests for Android implementation on CI #22
  • iOS plugin implementation tests
• Add action to check linter issues
• Add some linter styling setup so the structure of the project remains stable over time

Maybe linter with some custom rules

• Add Danger to check that each PR name is following convetional commits
• Automate deploys
  • ci(Deploy): automate deploy #49 and hotfix(Ignore): Update .gitignore for add file credentials #50
  • Fix ci deployment: Support automated publishing from CI dart-lang/pub-dev#5388 and Can not deploy from CI with personal credentials.json sakebook/actions-flutter-pub-publisher#30
