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
