Flutter Course

This is a just a study guide or a guide when programming in Flutter. It has only the links to specific material. It does not intend to be a manual on Flutter.

Some Flutter resources:

a. Overview of Flutter - The official homepage for the Flutter framework, providing a high-level introduction, showcases, and news. b. the main documentation - The landing page for Flutter's official documentation, the most critical resource for any developer. In particular, there is a page that is a cook book - A collection of practical, recipe-style guides for solving common problems and implementing specific features. c. Comunidade Flutter do Brasil - The main hub for the Brazilian Flutter community, offering articles, tutorials, and events in Portuguese. d. Heyflutter - A popular YouTube channel with concise, high-quality tutorials on a wide range
