graphql

graphql/client.dart is a GraphQL client for dart modeled on the apollo client, and is currently the most popular GraphQL client for dart. It is co-developed alongside graphql_flutter on github, where you can find more in-depth examples. We also have a lively community alongside the rest of the GraphQL Dart community on discord.

As of v4, it is built on foundational libraries from the gql-dart project, including gql, gql_link, and normalize. We also depend on hive for persistence via HiveStore.
