florval 0.2.3

Generate type-safe Flutter/Dart API clients from OpenAPI specs. Freezed models, status-code Union types, and Riverpod 3.x integration.

0.2.3

Bug Fixes

• Fix ambiguous exports for union type subclass names: Resolve dart analyze errors caused by union variant subclass names (e.g., RequestDataRoomInvitation) being exported from both the union type file and a standalone model file. Implemented 3-layer defense:
  1. Clean output directory before generation to remove stale files from previous runs
  2. Pre-filter variantSchemaNames() to exclude discriminator union variants from standalone model generation
  3. Barrel-level deduplication via unionSubclassNames() as a safety net to remove colliding names from exports
• Fix variant schema filtering for inline unions: Only use component schemas (not inline union schemas from response bodies) for variant filtering, preventing independent component schemas like EventNotFoundErrorDto from being incorrectly excluded

0.2.2

Improvements

• Update package description to be more concise and highlight core features (Freezed models, status-code Union types, Riverpod 3.x)
• Add encer.co.jp vision statement to README

0.2.1

Features

• Inline enum generation: Generate Dart enums from inline OpenAPI enum properties, instead of requiring top-level schema definitions
• readOnly / writeOnly support: Read OpenAPI readOnly and writeOnly flags on schema fields and propagate them to the intermediate representation
• Doc comments and example output: Generate /// doc comments from OpenAPI description fields and /// Example: ... from example values on models, fields, enums, and endpoints
• default value support: Read OpenAPI default values and generate @Default(...) annotations in freezed models. Supports string, integer, number, boolean, empty array, and enum types. DateTime and non-empty array defaults emit a warning and are skipped. Fields with both required and default use @Default(...) (freezed does not allow both)
• deprecated flag support: Read OpenAPI deprecated flags at schema, property, operation, and parameter levels and generate @Deprecated('') annotations. Schema-level deprecated applies to class/enum definitions; property-level deprecated applies to individual fields; operation/parameter-level deprecated applies to client methods and their parameters
• Schema title fallback for doc comments: Use schema title as doc comment when description is not available

Bug Fixes

• Preserve properties in _applyAbsentable: Fix example, readOnly, and writeOnly fields being lost when _applyAbsentable transforms optional fields for PATCH/PUT request bodies
• Operation/Parameter deprecated field name: Fix incorrect property name used when reading the deprecated flag from Operation and Parameter objects
• Null safety in doc comment generation: Fix null safety operator for description and example in doc comment generation

0.2.0

Breaking Changes

• Rename response Union types from {Op}Response to {Op}ApiResponse to structurally resolve name collisions with model classes
• Switch response Union types from freezed to plain Dart sealed classes (copyWith/equality/fromJson not needed, eliminates build_runner dependency for response types)

Features

• JsonOptional<T> for PATCH/PUT partial updates: Generate JsonOptional<T> sentinel type that distinguishes "key absent" (unchanged) from "key is null" (clear value) at the type level. Optional fields in PATCH/PUT request bodies are wrapped in JsonOptional<T> with @Default(JsonOptional<T>.absent()). Custom fromJson uses json.containsKey() for 3-state restoration; custom toJson excludes absent keys. @Freezed(fromJson: false, toJson: false) bypasses json_serializable entirely for absentable schemas. POST request bodies and response models are unaffected.
• Inline anyOf/oneOf union type support: Detect anyOf/oneOf declared inline within schema properties and automatically generate Union types for them
• Restore freezed for discriminator union types: Generate @Freezed(unionKey: '...') + @FreezedUnionValue('...') with variant fields inlined into factory constructors
• Non-discriminator union fromJson/toJson: For oneOf/anyOf without a discriminator, generate fromJson that tries each variant sequentially and toJson that branches on runtimeType
• Logger warnings: Emit warnings when an array type is missing items or when an unsupported content-type is encountered

Bug Fixes

• anyOf/oneOf nullable $ref pattern: Fix anyOf: [{$ref: '#/.../Foo'}, {type: 'null'}] incorrectly resolving to Map<String, dynamic> instead of a nullable type
• additionalProperties typed Map: Generate correct Map<String, T> type when additionalProperties specifies a schema
• ResponseAnalyzer nullable anyOf: Fix false detection of nullable anyOf patterns during response analysis
• _extractType dynamic fallback: Fix dynamic fallback handling when type extraction fails
• Inline object fallback: Fix inline object schemas incorrectly falling back to Map<String, dynamic> instead of generating proper types
• Inline oneOf/anyOf responses: Fix inline oneOf/anyOf in endpoint response definitions falling back to Map<String, dynamic>
• allOf + nullable $ref: Fix resolution of nullable $ref entries within allOf compositions
• List<dynamic> type error: Fix type inference error in florval_runner schemas variable
• Name collision structural fix: Resolve response Union type vs. model class name collisions using import prefix splitting and barrel file separation
• json_serializable sealed class error: Fix json_serializable errors on sealed class fields with discriminator
• .g.dart part directive exclusion: Skip unnecessary .g.dart part directive generation for sealed classes with discriminator
• Library import prefix lint: Remove leading underscores from generated import prefixes to fix no_leading_underscores_for_library_prefixes lint violation
• includeIfNull: false revert: Revert @JsonSerializable(includeIfNull: false) addition due to incompatibility with demo-api default values; fix applied on API side instead

Refactoring

• Analyzers as pure functions: Convert SchemaAnalyzer, EndpointAnalyzer, and ResponseAnalyzer to stateless pure functions for improved testability (+477/-305 lines)
• FlorvalRunner phase splitting: Clearly separate Parse → Resolve → Analyze → Generate → Write phases with an AnalysisResult intermediate representation
• Generator layer deduplication: Extract shared status code conversion and import collection logic from client_generator / response_generator into utils/status_code.dart and utils/import_collector.dart (+72/-115 lines)
• Import deduplication: Reduce unnecessary import generation in provider generator
• Test readability improvements: Unify formatting and structure in model_generator_test, remove unnecessary forced unwraps in response_analyzer_test
• Deduplicate toJson serialization logic: Unify _writeToJsonField and _toJsonValueExpression in ModelGenerator — _writeToJsonField now delegates to _toJsonValueExpression, eliminating duplicated type-dispatch logic (DateTime, enum, List, reference types)
• Barrel file separation: Exclude api_responses.dart from api.dart re-exports, keeping only models/clients/providers

Demo / Example

• Add demo-api server: Hono + @hono/zod-openapi based mock API server with full endpoint coverage (auth, CRUD, file upload, notifications)
• Add Flutter Web project: Flutter Web example app connecting to demo-api at localhost:3000
• Add CLI verification script: example/lib/verify.dart for integration testing against demo-api
• Update example generated code: Regenerate all code based on demo-api OpenAPI spec (6 tags, 15 response types, 35 models)
• Remove unused files: Delete petstore-derived API client, model, provider, and response files

0.1.1

Bug Fixes

• Fix empty-property schema causing build_runner error

Improvements

• Expand Riverpod reserved name handling with generated super params
• Rename Riverpod reserved param names in generated providers
• Handle non-ASCII characters in field names and enum values
• Generate mutation helper functions even when no GET endpoints exist in tag
• Remove unnecessary dart:async import from generated providers

• Always generate part directive and riverpod_annotation import in providers
