How is this section of the app laid out

• The section of the app can be accessed through the main activity - contribute screen
• AddPropertyFormContainer composable is treated as a parent composable for hosting several child Composables
• An instance AddPropertyFormViewModel used for AddPropertyFormContainer is shared among AddressForm, AmenitiesForm, PictureDescForm and ReviewForm. (This allows to consolidate all the information collected in the form in a single ViewModel and also allows to maintain state of different form pages when moving back and forth between form pages)
• Static data for drop down boxes used in the forms are loaded by the AddPropertyFormViewModel json files in the assets folder. Having this information as a json file makes updates flexible as the source code need not be changed.
• The parsers for the static json files in assets are done using a Gson based parser. The parser was supposed to be made generic but due to a currently open issue in Gson the parsers are separate for each file.
