Guess the Thing

This app loads data from https://uaserials.pro/cartoons/, the end result is a list of cartoons. App randomly picks one Cartoon from the list which is the right answer and randomly picks 3 names of other cartoons that != right answer. CountDown timer makes quiz limited by time (30 sec). After 30 seconds your result is saved to DataStore Preference.

What I used in this project:

• Jetpack Compose with Jetpack Navigation
• Koin DI
• Coroutines
• Ktor Client
• Room
• DataStore Preferences
• Coil

DataStore:

    private val Context.dataStore: DataStore<Preferences> by preferencesDataStore(name = "quiz_result")
    private val MAX_RESULT_KEY = intPreferencesKey("max_result")
    
    suspend fun saveMaxResult(result: Int) {
        context.dataStore.edit { preferences ->
            val maxResult = preferences[MAX_RESULT_KEY] ?: 0
            if (result > maxResult) {
                preferences[MAX_RESULT_KEY] = result
            }
        }
    }

    fun getMaxResult(): Flow<Int> {
        val getResult = context.dataStore.data.map { preferenses ->
            preferenses[MAX_RESULT_KEY] ?: 0
        }
        return getResult
    }
    

CountDown Timer:

   suspend fun quizCountDown(time: Int, navAction: () -> Unit) {
    if (time > 0) {
        var funTime = time
        while (funTime != 0) {
            funTime--
            delay(1000)
        }
        navAction()
    }
}
