Remove todos - Mutation

In this part of the tutorial, you will learn how to remove existing todos by using GraphQL Mutations.

Let's define a GraphQL query to do a mutation in todos.

Copy
mutation delete($id:Int!) {
 action: delete_todos(where: {id: {_eq: $id}}) {
    returning {
      id
    }
  }
}

Try this mutation in GraphiQL against the application database to see what the response looks like.

Let's now integrate this GraphQL mutation into our Flutter app.
