Description:

os basecode

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 #

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
copied to clipboard
getNumberOnly #
use getNumberOnly for convert string currency to number
var formatted = "Rp. 10.000"
var number = getNumberOnly(formatted);
print(number) // 10000
