Request: Add `GetIt.I.replace` for simpler testing

[esDotDev]

Instead of writing:

if(testing){
    GetIt.I.unregister<BlueToothService>();
    GetIt.I.registerLazySingleton<BlueToothService>(() => BlueToothServiceMock());

    GetIt.I.unregister<PurchasesManager>();
    GetIt.I.registerLazySingleton<PurchasesManager>(() => PurchasesManagerMock());
}

It would be nice to write:

if(testing){
     GetIt.I.replace<BlueToothService>(() => BlueToothServiceMock());
     GetIt.I.replace<PurchasesManager>(() => PurchasesManagerMock());
}

Maybe there is something for this already and I'm just missing it? I tried resetLazySingleton but it didn't work as I expected.

I guess scope would be the recommended way of doing this?

if(testing){
     GetIt.I.pushNewScope();
     GetIt.I.registerLazySingleton<BlueToothService>(() => BlueToothServiceMock());
     GetIt.I.registerLazySingleton<PurchasesManager>(() => PurchasesManagerMock());
}

This probably makes this feature request redundant, but maybe .replace is still worthwhile to have in the name of simplicity?

Maybe

  /// By default it's not allowed to register a type a second time.
  /// If you really need to you can disable the asserts by setting[allowReassignment]= true
  bool allowReassignment = false;

might solve your problem?

Ah interesting, thx Thomas!
