async_snapshot_exts library

Extensions

AsyncSnapshotResultExtension on AsyncSnapshot<T>

Extension methods on AsyncSnapshot that provide a Result-like API similar to Kotlin and Rust's Result class, but with an additional "pending" state.

Functions

err<T>(Object error, [StackTrace? stackTrace]) → AsyncSnapshot<T>

Creates an AsyncSnapshot with an error (equivalent to Result.err)

fromFuture<T>(Future<T> future) → Future<AsyncSnapshot<T>>

Boxes a Future into an AsyncSnapshot (i.e. captures errors into a snapshot)

ok<T>(T value) → AsyncSnapshot<T>

Creates an AsyncSnapshot with a successful value (equivalent to Result.ok)

pending<T>() → AsyncSnapshot<T>

Creates a pending AsyncSnapshot (equivalent to Result.pending)
