Description
Hi. For the last few years I've been working with C# and now using Dart and Flutter in personal and job projects.
And I feel the need in the interfaces as the aspect of Dart language.
I understand, that abstract classes provides the similar ways to get the guaranties about the interaction interface in the inherited children. But the interfaces will provides more strict understanding, about some entity behavior, and we could be sure, that our child won't inherit some useless behavior from the abstract parent.
