This is an excerpt of my pubspec.yaml file:
flutter:
uses-material-design: true
fonts:
- family: Coiny
fonts:
- asset: fonts/Coiny-Regular
I tried everything but the changes in pubspec.yaml just did not make any difference. I then created a new project. copied font files to respective folder, made all changes to pubspec.yaml, pasted code into my main.dart file. I ensured everything was in place and then ran project in simulator and viola all fonts appeared in full glory.
