jsonexample

A Flutter sample app that deserializes a set of JSON strings using three different libraries: dart:convert, json_serializable, and built_value.

Goals for this sample

  • Help you decide which of the three most common libraries for deserializing JSON is right for your project.
  • Provide you with example code for deserializing:
    • Simple and nested objects
    • Lists of primitive values
    • Maps containing primitive values

The important bits

json_strings.dart

The actual JSON to be deserialized.

dart_convert/json_serializable/dart_convert

These folders contain code used to deserialize the simple and complex object models using one of the three libraries. They do the work of instantiating models and populating their fields.

tab_pages.dart

Each tab page in the app deserializes one type of data with one library. These Widgets show what app code using the above libraries might look like.
