flutter_spine 0.2.2

Shared infrastructure for Flutter apps — MVVM base classes, effect bus, scaffold suite, network layer, and error model.

0.2.2

Added

• BaseWsGateway — abstract WebSocket gateway for business modules. Delegates connection lifecycle to WsClient; subclasses (Market / Asset / Swap) define type-safe subscription APIs and topic encoding.
• WsClientConfig.headersProvider — dynamic headers callback. Called on every connect / reconnect to fetch the latest token, eliminating the need to rebuild config after auth refresh.
• WsClientConfig.queryParamsProvider — dynamic query string callback. Same pattern as headersProvider, for backends that pass auth tokens via URL query params (?token=xxx) instead of HTTP headers. Manual string concatenation avoids Dart SDK Uri.replace() port :0 bug.
• WsClientConfig.onAuthExpired + isAuthCloseCode — token expiry auto-refresh. When the server closes with an auth close code (e.g. 4001), DefaultWsClient calls onAuthExpired with single-flight guarantee, then reconnects with the new token. Unsuccessful refresh transitions to WsFailed.
• Close code handling in DefaultWsClient — normal close codes (1000, 1001) now transition to WsDisconnected without triggering auto-reconnect. All other close codes continue to trigger standard reconnect.
• Unified IOWebSocketChannel in _defaultFactory — always uses IOWebSocketChannel.connect(), no longer implicitly switches between WebSocketChannel.connect() and IOWebSocketChannel based on parameter presence. Behavior is now consistent regardless of whether headers/queryParams are configured.
• WsTopicRouter.simple() — factory constructor for standard pub/sub protocols where channel name equals topic name. Auto-generates topicExtractor, subscribeFrameBuilder, and unsubscribeFrameBuilder from a single channelKey parameter.
• WsModuleRegistry + WsModuleConfig — registration pattern for WebSocket modules. Each business module defines a WsModuleConfig instance; WsModuleRegistry.build() maps URIs to configs, replacing hand-written if-else chains in wsConfigBuilderProvider overrides.
• CLI ws-gateway command — flutter_spine:new ws-gateway <name> generates topic / topic_router / ws_gateway / providers four-file scaffold.

Changed

• Breaking: WsClientConfig.headers replaced by headersProvider (Map<String, dynamic> Function()?). Existing code must change from headers: {'key': 'val'} to headersProvider: () => {'key': 'val'}.
• WsClientConfig constructor now accepts headersProvider, queryParamsProvider, onAuthExpired, and isAuthCloseCode (all optional).
• _defaultFactory no longer branches on parameter presence — always constructs IOWebSocketChannel for consistent behavior.

Tests

• 7 new test cases for close code handling and auth refresh (33 total in test/network/ws/).

Example

• demo_market_ws/ — full MarketWsGateway implementation: topic encoding/decode (MarketTopic), protocol adapter (marketTopicRouter), Riverpod StreamProvider.autoDispose.family for automatic subscription lifecycle, and interactive lifecycle demo page.
• demo_asset_ws/ & demo_swap_ws/ — showcase multi-module Gateway pattern. All three modules share the same auth/heartbeat/reconnect config via a _sharedWsConfig factory in main.dart, each overriding only its own topicRouter.
• main.dart now demonstrates FlutterSpineConfig.extraOverrides with WsModuleRegistry.build() replacing the if-else chain.

0.1.2

Added

• PagedListView.scrollViewBuilder — embed the list in a CustomScrollView with extra slivers.
• PagedListView.enableLoadMore — disable load-more footer, keep only pull-to-refresh.
• AppListPageScaffold.scrollViewBuilder / enableLoadMore — forwarded to PagedListView.
• PagedScrollViewBuilder typedef.
• Example demo pages: /demos/paged-list, /demos/app-list.

Fixed

• DioExceptionType.transformTimeout not found with dio 5.9.x — replaced with default / _ fallback for forward compatibility.

0.1.1

Added

• Scaffold CLI (flutter_spine:new).
• generator_templates.dart — riverpod_generator support.
• FeatureCommand — flutter_spine:new feature one-key whole feature generation.
• BootstrapCommand — flutter_spine:new bootstrap app skeleton.
• FlutterCoreDiagnosticsBanner.
• MaterialDefaultEffectHandler ctor overrides.
• mixin-based API: ViewModelMixin, AsyncViewModelMixin, family variants.

Changed

• CLI templates now use {{Name}} / {{name}} / {{name_snake}} / {{name-kebab}} / {{Title}} naming conventions.
• Renamed FlutterCore to FlutterSpine, FlutterCoreConfig to FlutterSpineConfig.
