Summary

A package inspired by Rust and functional programming, designed to bring structure, clarity, and safety to your Dart applications.

Dart traditionally uses nulls and try-catch blocks, which can introduce runtime errors and complicate error handling. In contrast, languages like Rust prioritize safer error handling through types like Result and Option, ensuring explicit handling at compile time.

This package introduces Result and Option types to Dart, reducing the reliance on try-catch blocks and nulls. By leveraging these constructs, you can write more predictable, maintainable, and error-resilient code.

For a full feature set, please refer to the API reference.

Usage Example

Example of avoiding try-catch blocks in Dart, to produce safer code:

import 'package:df_safer_dart/df_safer_dart.dart';

import 'dart:convert';
import 'package:http/http.dart' as http;

void main() async {
  fetchIpAddress().fold(
    (value) => print('IP address: $value'),
    (error) => print('Error: $error'),
  );
}

Result<String> fetchIpAddress() {
  return Result(() async {
    final response = await http.get(Uri.parse('https://api.ipify.org?format=json'));
    // This throws an exception if the status code is not 200.
    PanicIf(response.statusCode != 200, 'Failed to fetch IP address');
    final data = jsonDecode(response.body);
    final ip = data['ip'] as String;
    // Return the result.
    return ip;
  });
}
