build method

@override ThemeMode build()

Initialize a Notifier.

It is safe to use Ref.watch or Ref.listen inside this method.

If a dependency of this Notifier (when using Ref.watch) changes, then build will be re-executed. On the other hand, the Notifier will not be recreated. Its instance will be preserved between executions of build.

If this method throws, reading this provider will rethrow the error.

Implementation

@override
ThemeMode build() {
  final savedTheme = ref.read(storageServiceProvider).getString(_themeKey);
  return ThemeMode.values.firstWhere(
    (e) => e.name == savedTheme,
    orElse: () => ThemeMode.system,
  );
}
