flutter-freezed plugin

Dart is awesome, but defining a "model" can be tedious. We may have to:

• define a constructor + the properties
• override toString, operator ==, hashCode
• implement a copyWith method to clone the object
• handling de/serialization

On top of that, Dart is also missing features such as union types and pattern-matching.

Implementing all of this can take hundreds of lines, which are error-prone and the readability of your model significantly.

Freezed tries to fix that by implementing most of this for you, allowing you to focus on the definition of your model. https://pub.dev/packages/freezed

Creating these models by hand becomes even more complex when you are working with a GraphQL server that can handle nested mutations.

See this GraphQL Playground and ask yourself, how would I create a model to handle this nested mutation?

Please change the address in the playground to use https instead of ~~http~~

# Write your query or mutation here
mutation createProgramme{
  createProgramme(input: {
    title: "GraphQL + Flutter",
    programmeCode: "graphql-dart-flutter-101",
    startLevel: 100,
    endLevel: 100,
    programmeOutlines: {
      create: {
        level: 100,
        course: {
          create:{
            title: "Flutter Freezed",
            courseCode: "CS-FF-101",
            books: {
              create:{
                title: "GraphQL is way awesome",
                author: "Parables Boltnoel"
              }
            }
          }
        }
      }
    }
  }){
    id
    title
    programmeCode
    programmeOutlines{
      level
      course{
        books{
          id
          title
          author
        }
      }
    }
  }
}

Fortunately enough, GraphQL is strongly typed, and so is Dart. Save yourself from implementing a model to match your strongly typed GraphQL operations, and let Freezed handle the work while you chill with this flutter-freezedplugin
