setTheme method

Future<void> setTheme(String themeId, { bool remember = false, })

Set the current theme by ID.

This will automatically disable followSystemTheme. To change theme while keeping system following enabled, use setFollowSystemTheme.

themeId - The ID of the theme to set. remember - If true, sets this theme as the preferred theme for its type (light or dark). This is used when following system theme to remember which theme variant the user prefers.

Implementation

Future<void> setTheme(String themeId, {bool remember = false}) async {
  final theme = getThemeById(themeId);
  if (theme == null) {
    throw ArgumentError('Theme with id "$themeId" not found.');
  }

  // Disable follow system theme on manual set
  if (_followSystemTheme) {
    _followSystemTheme = false;
    await _storage.saveFollowSystem(false);
  }

  // Optionally remember this theme as preferred for its type
  if (remember) {
    if (theme.type == NyThemeType.dark) {
      _preferredDarkThemeId = themeId;
      await _storage.savePreferredDarkThemeId(themeId);
    } else {
      _preferredLightThemeId = themeId;
      await _storage.savePreferredLightThemeId(themeId);
    }
  }

  _setThemeInternal(themeId, notify: true, persist: true);
}
