thenLeft<TL> method

Future<Either<TL, R>> thenLeft<TL>(
  1. FutureOr<Either<TL, R>> fnL(
    1. L left
    )
)

Async transform value of Left when transformation may be finished with an Right

Implementation

Future<Either<TL, R>> thenLeft<TL>(
        FutureOr<Either<TL, R>> Function(L left) fnL) =>
    this.then((either) => either.thenLeftAsync(fnL));
