To continue on your Flutter journey, in this course you’ll build an app named RW Courses.

Demo

To get started working with a new Flutter project, a good habit is to run Flutter doctor to make sure everything is working as designed. Now, I’m using macOS command-spacebar to access the terminal. If you are using windows, you can search for command line by searching from the start menu.

command-space (search terminal)
flutter doctor

class Strings {
  static String appTitle = 'RW Courses';
  static String filter = 'Filter';
  static String ios = 'iOS';
  static String android = 'Android';
  static String flutter = 'Flutter';
  static String unity = 'Unity';
  static String sss = 'Server-Side Swift';
  static String macos = 'macOS';
  static String archived = 'Archived';
  static String all = 'All';
  static String unknown = 'Unknown';
}
