parsley

Simplifies your code by unifying all parsing logic into a single simple call.

Easily extendable by enabling you to register your own custom parsing functions.

import 'package:parsley/parsley.dart';

void main() {
  DateTime date = parse("2020-02-12");
  int textToInt = parse("5");           // 5
  bool textToBool = parse("true");      // true
  int stringToInt = parse("5");         // 5
  String intToString = parse(5);        // "5"
  bool intToBool = parse(1);            // true
  int doubleToInt = parse(5.5);         // 5
  double stringToDouble = parse("5.5"); // 5.5
  List<String> intToStringList = parse([1, 8, 3]); // ['1', '8', '3']
  List<int> StringListToIntList = parse(["1", "8", "3"]);
}
