TypeMapper class

Maps GraphQL types to Dart types for code generation.

Handles custom scalars, enums, and configured type overrides from .zfa.json.

Spec 037 additions:

Constructors

TypeMapper({Map<String, String>? customScalars, Map<String, String>? typeOverrides})
TypeMapper.fromZfaConfig(Map<String, dynamic> zfaJson): Builds a mapper from a parsed .zfa.json document, reading graphql.scalarMap (GraphQL scalar name → Dart type name).
factory

hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

interfaceRepresentation(GraphQLInterfaceType type) → String: Renders a Dart abstract class for a GraphQL interface type: declared fields become abstract final fields with mapped Dart types (FR-008).
mapType(GraphQLType type) → String: Map a GraphQLType to its Dart equivalent.
mapTypeRef(GqlTypeRef ref) → String: Maps a raw introspection GqlTypeRef (from GqlSchema) to a Dart type string, following the same conventions as mapType. Used by the diff/codegen paths that work on the introspection model directly.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
inherited
unionRepresentation(GraphQLUnionType type) → String: Renders a Dart sealed class hierarchy for a GraphQL union type: every member type gets a typed variant class so all members remain accessible with their concrete types (FR-008).

className(String graphQLName) → String: Map a GraphQL type name to a Dart class name (PascalCase, reserved built-in type collisions escaped — spec 037 FR-007).
enumValue(String graphQLValue) → String: Map a GraphQL enum value to a Dart enum value (camelCase).
fieldName(String graphQLName) → String: Map a GraphQL field name to a Dart field name (camelCase, reserved words escaped — spec 037 FR-007).
