LevelThemes class

Maps game levels to themes so colors change as the player levels up.

Each level uses the next palette in palettes, wrapping around after the last one. Themes are built once, so the same level always returns the same TetrisTheme instance.

final levelThemes = LevelThemes(base: darkTetrisTheme);

LevelThemeBuilder(
  game: game,
  levelThemes: levelThemes,
  builder: (context, theme, _) => TetrisBoard(game: game, theme: theme),
);

Constructors

LevelThemes({required TetrisTheme base, List<LevelPalette>? palettes, int levelsPerPalette = 1, bool? recolorBoard})

When recolorBoard is null, board colors are replaced only if base has a dark board, so the built-in dark palettes do not clash with light themes' text styles.
