Basic Functionality

Failur Class

Use Failure Class On Reporitory Implement for Return On Left Type Either

ServerFailure
ConnectionFailure
CommonFailure
DatabaseFailure

Examples:

  Future<Either<Failure, List<PriceInfoEntity>>> fetchAllGroup() async {
    try {
      var result = await alertRemoteDataSource.fetchAllGroup();
      return Right(result.map((e) => e.toEntity()).toList());
    } on DatabaseException catch (e) {
      return Left(DatabaseFailure(e.message));
    } on ServerException {
      return const Left(ServerFailure("Your message here"));
    } on CommonException{
        return const Left(CommonFailure("Your message here"));
    } catch (e) {
      return const Left(DatabaseFailure("Your message here"));
    }
  }

Exception Class

Use Exception Class On Datasource for Throw, and then catch the throw on Repository Implement

ServerException
DatabaseException
CommonException

Examples:

Future<List<PriceInfo>> fetchAllGroup() async {
    try {
      Dio dio = Dio();
      var result = await dio.get(priceInfoURL);
       return priceInfoFromJson(result.data);
    } on DioError {
      throw ServerException();
    } catch (e) {
      throw DatabaseException();
      //common exception
      throw CommonException();
    }
  }

Client Class

Client Class is Customized DIO implementation that can be used, its customable properties like baseURL, headers, showLogging

Example:

Initialize a simple client, without any headers:

var client = Client(baseURL: "your_base_url", showLogging: true, headers: {}, handleWhenUnauthorized: (){
  //Handle your 401 exception here
})..init();

Use client on your data_source: assume we already inject the client using dependencies injection

Class GroupRemoteDataSourceImpl implement GroupRemoteDataSource {
    Dio dio;
    GroupRemoteDataSourceImpl(this.client);

    Future<List<PriceInfo>> fetchAllGroup() async {
    try {
      var result = await dio.get(priceInfoURL);
       return priceInfoFromJson(result.data);
    } on DioError {
      throw ServerException();
    } catch (e) {
      throw DatabaseException();
    }
  }
}

Utility Methods

debounce

use debounce on bloc transformer Example:

on<OnQueryBanner>((event, emit) async {
    // Your BLoC Code here
}, transformer: debounce(const Duration(milliseconds: 500)));

NumericTextFormatter

use NumericTextFormatter inside Textformfiel inputFormatter Example:

return TextFormField(
        controller: nominalController,
        inputFormatters: [
          FilteringTextInputFormatter.digitsOnly,
          NumericTextFormatter()   // <----- ADD HERE
        ],
        keyboardType: TextInputType.number,
);

formatRupiah

use formatRupiah to convert number to string currency Example:

var nominal = 1000
var formatted = formatRupiah(nominal);
print(formatted) // Rp. 10.000

getNumberOnly

use getNumberOnly for convert string currency to number

var formatted = "Rp. 10.000"
var number = getNumberOnly(formatted);
print(number) // 10000
