This is aimed for complete beginners in Flutter, to get them acquainted with the various basic widgets in Flutter.
- Fork this project.
- Rename the directory to "flutter_widgets" or something with all_lowercase_and_underscore. (Unfortunately Flutter doesnt like CamelCases)
- In your terminal, run
flutter create .This will create the android and iOS projects for you. - Run in your emulator or simulator.
OR you can always copy the examples from here and try it out in your apps.
