[Feature]: Allow editing cache

[jtdLab]

Problem

When creating/updating data on a remote data source developers might want to update the local cache after that.

Desired Solution

In the most basic cases something like this could solve it.

Create:

// foo_repository.dart

  @EditCache
  Future<Foo> createFoo(Foo foo) async {
    await dataSource.create(foo);
    return foo;
  }

leading to

// foo_repository.cached.dart

  @override
  Future<Foo> createFoo(Foo foo) async {
    final result = await super.createFoo(foo);
    _getFooCached["${foo.hashCode}"] = result;
    return result;
  }

Update:

// foo_repository.dart

  Future<Foo> getFoo() async {
    // ...
  }

  @EditCache
  Future<Foo> updateFoo(int a, String b) async {
    await dataSource.update(a, b);
    final foo = getFoo();
    return foo.copyWith(a:a, b:b);
  }

leading to

// foo_repository.cached.dart

  @override
  Future<Foo> updateFoo(int a, String b) async {
    final result = await super.updateFoo(a, b);
    _getFooCached["${foo.hashCode}"] = result;
    return result;
  }
