gistfile1.txt

class WidgetRepository @Inject constructor(@ApplicationContext val appContext: Context) {

    private var _currentTitle = MutableStateFlow<String?>("")
    val currentTitle = _currentTitle.asStateFlow()

    @EntryPoint
    @InstallIn(SingletonComponent::class)
    interface WidgetRepoEntryPoint {
        fun widgetRepo(): WidgetRepository
    }

    companion object {
        var _instance: WidgetRepository? = null
        fun get(appContext: Context): WidgetRepository {
            if (_instance == null) {
                val entryPoint: WidgetRepoEntryPoint =
                    EntryPoints.get(appContext, WidgetRepoEntryPoint::class.java)
                _instance = entryPoint.widgetRepo()
            }
            return _instance!!
        }
    }

    fun updateEpisodeTitle(s: String) {
        _currentTitle.value = s
    }

}
