  //```codec
  const t = TextStyleCodec();
  //```
  if (data == null || data.isEmpty) return null;
  return TextTheme(
    displayLarge: t.decode(data['displayLarge']),
    displayMedium: t.decode(data['displayMedium']),
    displaySmall: t.decode(data['displaySmall']),
    headlineLarge: t.decode(data['headlineLarge']),
    headlineMedium: t.decode(data['headlineMedium']),
    headlineSmall: t.decode(data['headlineSmall']),
    titleLarge: t.decode(data['titleLarge']),
    titleMedium: t.decode(data['titleMedium']),
    titleSmall: t.decode(data['titleSmall']),
    bodyLarge: t.decode(data['bodyLarge']),
    bodyMedium: t.decode(data['bodyMedium']),
    bodySmall: t.decode(data['bodySmall']),
    labelLarge: t.decode(data['labelLarge']),
    labelMedium: t.decode(data['labelMedium']),
    labelSmall: t.decode(data['labelSmall']),
  );
