Haskell-like functionality for Dart

Features

• ✅ Open Source
• ✅ Fully Tested and Documented
• ✅ Lightweight and Fast
• ✅ Pure Dart (no Flutter dependencies)
• ✅ Cross-platform

Types

• Maybe<T> - Represents a value or the absence of a value.
• Either<L, R> - Represents a value of type L or a value of type R
• Result<T> - Represents the result of a computation, either succeeding with a value, or failing with an error
• RandomVariable<T> - Describes a variable with a random component, allowing for lazy evaluation and other utilities (convenient reuse/caching/mocking). Inspired by Haskell's strict handling of randomness

Extensions

• Iterable
  • head, tail, init, lastMaybe (to avoid naming conflicts)
  • fold1 - like fold but without an initial value
  • scan and scan1 - like fold, but returning an Iterable of all intermediate values
  • intersperse - inserts elements in between existing elements
• int
  • 1.to(5) - a replacement for Haskell's [1..5]
  • 1.toInfinity() - a replacement for Haskell's [1..]

And More

• curry and uncurry - easy partial function application in Dart
• repeat and Iterable.cycle - create a list of repeating values
