Graphql codegen

graphql_ast_visitor

Provide abstract layer to visit graphql ast nodes.

dart_gen

Generate dart codes from graphql ast nodes.

Run dart_gen/example/main.dart to see full output from this graphql

You can also write some more gql files from gitlab to see more generated results.

Roadmap

Enginnering

• Unit tests
• CI
• Docs and Example website

Features

• Operations
• Variables
• Fragments
• Union Types
• Directives
