Master Detail project

POC of Master Detail flow with:

• simple named routing with parameters
• loading Image.network with local Image.asset placeholder
• parsing json collection object to data model
• scrollable ListView
• json_serializer
• filter on ListView

Json generation:

• add @JsonSerializable()
• implement fromJson and toJson methods (lib/shared/model/fruit.dart)
• add part 'fruit.g.dart';
• dont mind errors -> run generation tool below: make use of the watcher to rebuild json on model change: flutter pub run build_runner watch

ERROR: Generator cannot target libraries that have not been migrated to null-safety.

I found out that json_serializable >=4.0.0 depends on json_annotation >=4.0.0 <4.1.0 and the json_annotation: ^4.0.0 includes Null Safety but json_serializable: ^4.0.2
