1.In Android Studio, you need to create a package under lib folder. For example you create a package fonts (path is app_name/lib/fonts).

2.In the pubspec.yaml the code would look like:

flutter:
    fonts:
      - family: Oxygen
        fonts:
          - asset: app_widgets/lib/fonts/Oxygen-Regular.ttf
          - asset: app_widgets/lib/fonts/Oxygen-Bold.ttf
            weight: 700
          - asset: app_widgets/lib/fonts/Oxygen-Light.ttf
            weight: 300
