DynamicFontsFile class abstract

Describes a font file as it is expected to be received from the server.

If a file is retrieved and its hash does not match expectedFileHash, or it is not of expectedLength bytes length, the font will not be loaded, and the file will not be stored on the device.

Clients will need to subclass this to provide the correct URL. If the URL depends on the font variant, consider a pattern like this:

class MyFontFile extends DynamicFontsFile {
  FiraGoFile(this.variant, String expectedFileHash, int expectedLength)
      : super(expectedFileHash, expectedLength);

  final DynamicFontsVariant variant;

  @override
  String get url =>
      'https://example.com/MyFont-${variant.toApiFilenamePart()}.ttf';
}
