typed_llm_generator 0.2.0

build_runner code generator that turns @LlmSchema-annotated classes into JSON Schemas and validated-JSON factories for the typed_llm package.

0.2.0

Requires typed_llm ^0.2.0.

Added

• Every @LlmSchema() class now also generates $<Class>, a const LlmType<Class> binding <Class>Schema to _$<Class>FromValidatedJson. This is what you pass to Extractor.extract, and it is what makes the call type-safe — see typed_llm's 0.2.0 changelog for the mismatch it rules out.

Changed

• <Class>Schema and the generated members now carry dartdoc, so they no longer trip public_member_api_docs in projects that lint generated code.

Existing output is otherwise unchanged: <Class>Schema and _$<Class>FromValidatedJson keep their names and shapes, so a fromValidatedJson wrapper you already wrote still compiles. It is now redundant, though — $<Class> points at the factory directly.

0.1.0

Initial release.

• Requires Dart 3.9 or newer, and builds on the analyzer 2.0 element model (analyzer >=9.0.0 <15.0.0, source_gen ^4, build ^4). The analyzer range is deliberately wide so this generator co-resolves with whatever other codegen packages — freezed, json_serializable — pin in the same app. Verified against analyzer 10.2.0 and 12.1.0, including a resolve alongside freezed 3.x.

• LlmSchemaGenerator (build.yaml key llm_schema): turns an @LlmSchema()-annotated class into a <Class>Schema JSON Schema constant and a _$<Class>FromValidatedJson factory function.

• Supports primitives (String, int, double, num, bool), DateTime (as an ISO-8601 date-time string), enums (as a string enum), nullable fields, List<T>, and nested @LlmSchema classes — all resolved recursively and inlined into both the schema and the factory.

• Works on freezed classes: reads constructor parameters from a redirecting const factory constructor the same way it reads a plain generative one.

• Clear, actionable build-time errors for unsupported field types, positional constructor parameters, and @LlmField(optional: true) on a non-nullable field.
