Getting Started

Add SwissArmyKnife to a Dart or Flutter project and start using the single public import.

Install#

dependencies:
  swissarmyknife: ^0.1.0

dart pub get

Import#

import 'package:swissarmyknife/swissarmyknife.dart';

First Use#

final title = 'release_candidate'.toTitleCase();
final number = '42'.toIntOrNull();
final maybeUser = Option.fromNullable('Ada');

print(title);
print(number);
print(maybeUser.map((name) => name.toUpperCase()).getOrElse('UNKNOWN'));

Good Defaults#

Use SwissArmyKnife where it removes repeated glue:

Result for operations that may fail.
Validator for edge input before it reaches domain code.
SafeJson for map payloads from HTTP or storage.
TaskQueue and RateLimiter where concurrency and throughput matter.
CircuitBreaker around unreliable remote dependencies.

Platform Note#

The public barrel import is web-compilable. Env.load() reads files and is VM-only; use Env.fromMap() for browser and app-managed configuration.
