Classes

GraphExceptionErrorLocation
Information about a location in source text that caused an error during the execution of a GraphQL query.
GraphQLBoolType
GraphQLClass
Signifies that a class should statically generate a GraphQLSchema.
GraphQLDirectiveType
GraphQLDocumentation
A metadata annotation used to provide documentation to package:graphql_server.
GraphQLEnumType<Value>
A GraphQLType with only a predetermined number of possible values.
GraphQLEnumValue<Value>
A known value of a GraphQLEnumType.
GraphQLExceptionError
One of an arbitrary number of errors that may occur during the execution of a GraphQL query.
GraphQLFieldInput<Value, Serialized>
An input to a GraphQL field. This is analogous to a function parameter in Dart.
GraphQLInputObjectField<Value, Serialized>
A field expected within a GraphQLInputObjectType.
GraphQLInputObjectType
A special GraphQLType that specifies the shape of an object that can only be used as an input to a GraphQLField.
GraphQLListType<Value, Serialized>
A special GraphQLType that indicates that input vales should be a list of another type, ofType.
GraphQLNonNullableType<Value, Serialized>
A special GraphQLType that indicates that input values should both be non-null, and be valid when asserted against another type, named ofType.
GraphQLNumMaxType<T extends num>
GraphQLNumMinType<T extends num>
GraphQLNumRangedType<T extends num>
GraphQLNumType<T extends num>
GraphQLObjectField<Value, Serialized>
A field on a GraphQLObjectType.
GraphQLObjectType
A GraphQLType that specifies the shape of structured data, with multiple fields that can be resolved independently of one another.
GraphQLScalarType<Value, Serialized>
GraphQLSchema
The schema against which queries, mutations, and subscriptions are executed.
GraphQLStringMaxType
GraphQLStringMinType
GraphQLStringRangeType
GraphQLStringType
GraphQLType<Value, Serialized>
Strictly dictates the structure of some input data in a GraphQL query.
GraphQLUnionType
A special GraphQLType that indicates that an input value may be valid against one or more possibleTypes.
ValidationResult<Value>
Represents the result of asserting an input value against a GraphQLType.
