  /// A bitmap font that can be used with [drawString] and [drawChar] functions.
  /// If you want use own fonts following with this steps:
  ///     1. Get your .ttf file - important is to select file with specific style which you want
  ///         for example when you download .ttf file from google fonts: select file from /static folder
  ///         example name: Roboto-Black.ttf
  ///     2. Convert ttf file to fnt zip with page: https://ttf2fnt.com/
  ///     3. Create dart file with code:
  ///       void main() {
  ///         String fileName = 'YourFontName-Style.zip';
  ///         // your file has to be in the same folder as this program
  ///         File file = File('$fileName');
  ///         List<int> bytes = file.readAsBytesSync();
  ///         print(bytes);
  ///       }
  ///     4. Change fileName in code above to your file name
  ///     5. Run this program
  ///     6. Copy results
  ///     7. Create dart file in your project with code:
  ///       final BitmapFont fontNameSizeStyle = BitmapFont.fromZip(_FONTNAME_SIZE_STYLE);
  ///       const List<int> _FONTNAME_SIZE_STYLE = <PASTE_HERE>
