Here are a few examples of what this project offers: (click to expand) Immutable collections by default dart:core collections #ĭart's List is mutable by default. But sometimes they are too low level and not as straightforward as Kotlin's kotlin-stdlib. ![]() dependencies:ĭart's dart:core package provides basic building blocks. It's a useful addition to dart:core and includes collections ( KtList, KtMap, KtSet) as well as other packages which can improve every Dart/Flutter app. This project is a port of Kotlin's Kotlin Standard library for Dart/Flutter projects.
