Lightweight library for validating function arguments in Dart.
This library is mainly a port of Apaches org.apache.commons.lang3.Validate class
Validation is necessary on most public-facing APIs. Parameter validation on non-public methods is not as important - it is often desirable to have validation occur only once, at the public 'entry point' - but if you can live with the potential performance hit, I recommend to validate parameters everywhere, as it makes code maintenance and refactoring a bit easier.
For further documentation please refere to the Unit-Tests.
