FakeRandom class

A fake Random implementation that always produces a given sequence of values. It should only be used in tests.

Why prefer a FakeRandom over a seeded Random?

A FakeRandom avoids depending on implementation details. A seeded Random is implicitly dependent on the underlying PRNG algorithm. The generated values may change if the algorithm changes. Furthermore, reverse-engineering a seed is cumbersome.

Constructors

FakeRandom({Iterable<int> ints = const [], Iterable<double> doubles = const [], Iterable<bool> bools = const []})
