This patch release includes the following changes:

Miscellaneous

• #178 Allow analyzer 6

Notes created on Monday, November 04 04:27 PM UTC

• restrict analyzer to 5.x

• open analyzer range to 5

• reopen analyzer range

• only use nndb in generator if nndb feature is enabled. prevents build issues for non nndb consumers

• updated analyzer range to allow 2.x.x
• add gh action workflow

• updated analyzer, source_gen, build, build_test dependency ranges
• fix nnbd issues in generator
• set sdk range lower bound to 2.12.0

• add tests that generate actions with nullable generics
• fixed issue where ++ does not work on builder value
• address deprecations in generator
• Breaking changes:
  • The argements to ActionDispatcher.call are no longer optional. when dispatching an action a payload a value must be provided. if the payload type is nullable null must be explicitly provided. append a ? to the ActionDispatcher type parameter for any actions that can be dispatched with a null payload, e.g. ActionDispatcher<int?>.
  • Remove previously deprecated test method

• allow analyzer 0.39.0
• make dispatcher name public
• fix documentation typo

• add workiva_analysis_options
• remove usage of new keyword in code and examples
• bump various dependencies lower bounds

• add type_annotate_public_apis lint ignore to generated files

• rework generator to lift analyzer version constraint.
• open analyzer range
• generator now uses source parsing to resolve action generic types which allows any unresolved type to be used as an action payload.
• generated actions classes now use type inference.
• bump built_value lower bound to 6.1.4 since it is impossible for pub to resolve to anything lower due to the build dependency constraint.

• add built_redux_test_utils library - exposes an expectDispatched function for expecting a given action gets dispatched asynchronously
• add combine to MiddlewareBuilder class - lets you combine middleware builders
• add toString to Action class
• add example
• add docs

• add build.yaml and build.dart to comply with build_runner 0.7.x

With the dev tag you can consume the latest versions of built_value, build, and build_runner that are only compatable with dart 2.

In order to migrate:

• remove your old build scripts
• update your pubspec to include

  build_runner: ^0.7.9

• add a build.yaml to the root of your repo that contains the following:

targets:
  $default:
    builders:
      built_value_generator|built_value:
        enabled: false

• run pub run build_runner build.

The build script is only a temporary measure until https://github.com/dart-lang/source_gen/issues/319 is resolved.

• add changelog
• update readme to include link to todoMVC repo

• open dependency range on the build package

• open dependency range on the built_collection package

• dispose is now awaitable

• Added actionStream stream to the store api so one can listen to changes resulting from a specific action name.
• Fixed issues called out my adding implicit-dynamic and implicit-cast rules.

• Added reducer builders for all collection types in built_collection. This means you can now write reducers that rebuild just a collection. Examples: https://github.com/davidmarne/built_redux/blob/master/test/unit/collection_models.dart
• The action generator now supports inheritance, meaning one can now have action classes extend one another. AbstractReducerBuilder was added as means of merging a reducer builder defined to rebuild the abstract pieces of state. Examples: https://github.com/davidmarne/built_redux/blob/7.1.0/test/unit/inheritance_test_models.dart for examples

• Breaking changes:
  • A breaking change in behavior was made to action dispatchers. Before action dispatchers executed the middleware/reducers asynchronously, but they now execute synchronously.

For example you may have:

int getCount(store) {
  print(store.state.count); // prints 0
  store.actions.increment(1);
  print(store.state.count); // would print 1 if actions were sync, 0 if async
  return store.state.count; // would return 1 if actions were sync, 0 if async
}

Before this function would return 0 because the state update that occurs from actions.increment would be processed in a future task. Now this function will return 1 because the state update that occurs from actions.increment is processed in the current task

Removes the BuiltReducer interface and the generated BuiltReducer implementation in favor of building a reducer function and passing it to the store at instantiation.

• Breaking changes:
  • Store now takes a reducer
  • Nested reducers need to be built with the NestedReducerBuilder and merged wth the main ReducerBuilder using ReducerBuilder.addNestedReducer
  • Models no longer implement BuiltReducer
    • Remove references to the reducer on your models
  • Renamed ActionDispatcher.syncWithStore to setDispatcher
  • Renamed SubStateChange to SubstateChange

Reasoning:

• Decouples your models and reducers.
• Requires less generated code.
• Reducing requires less map look ups. Previously N map look ups were required where N was the number of BuiltReducers in your state tree. Now only 1 map look up is required per action dispatched.

Examples:

• Example model change. Remove the generated BuiltReducer mixin and the reducer getter

Before:

  abstract class Counter extends Object
     with CounterReducer
     implements Built<Counter, CounterBuilder> {
   int get count;

   get reducer => _reducer;

   Counter._();
   factory BaseCounter() => new _$BaseCounter._(count: 1);
 }

After:

  abstract class Counter implements Built<Counter, CounterBuilder> {
   int get count;

   Counter._();
   factory BaseCounter() => new _$BaseCounter._(count: 1);
 }

• Example nested reducer change. Change NestedCounter's reducer builder to a NestedReducerBuilder. Pass the NestedReducerBuilder mapper functions from the main state/builder to the nested state/builder.

Before

// Built Reducer
abstract class BaseCounter extends Object
    with BaseCounterReducer
    implements Built<BaseCounter, BaseCounterBuilder> {
  int get count;

  BuiltList<int> get indexOutOfRangeList;

  NestedCounter get nestedCounter;

  @override
  get reducer => _baseReducer;

  // Built value constructor
  BaseCounter._();
  factory BaseCounter() => new _$BaseCounter._(
        count: 1,
        nestedCounter: new NestedCounter(),
      );
}

final _baseReducer = (new ReducerBuilder<BaseCounter, BaseCounterBuilder>()
      ..add(BaseCounterActionsNames.increment, _baseIncrement)
      ..add(BaseCounterActionsNames.decrement, _baseDecrement))
    .build();

abstract class NestedCounter extends Object
    with NestedCounterReducer
    implements Built<NestedCounter, NestedCounterBuilder> {
  int get count;

  get reducer => _nestedReducer;

  // Built value constructor
  NestedCounter._();
  factory NestedCounter() => new _$NestedCounter._(count: 1);
}

final _nestedReducer =  (new ReducerBuilder<NestedCounter, NestedCounterBuilder>()
          ..add(NestedCounterActionsNames.increment, _nestedIncrement)
          ..add(NestedCounterActionsNames.decrement, _nestedDecrement))
        .build();

After

abstract class BaseCounter implements Built<BaseCounter, BaseCounterBuilder> {
  int get count;

  NestedCounter get nestedCounter;

  BaseCounter._();
  factory BaseCounter() => new _$BaseCounter._(
        count: 1,
        nestedCounter: new NestedCounter(),
      );
}

// the reducer passed to the store
final reducer = (new ReducerBuilder<BaseCounter, BaseCounterBuilder>()
      ..add(BaseCounterActionsNames.increment, _baseIncrement)
      ..add(BaseCounterActionsNames.decrement, _baseDecrement)
      ..combineNested(_nestedReducer))
    .build();

abstract class NestedCounter implements Built<NestedCounter, NestedCounterBuilder> {
  int get count;

  // Built value constructor
  NestedCounter._();
  factory NestedCounter() => new _$NestedCounter._(count: 1);
}

final _nestedReducer = new NestedReducerBuilder<BaseCounter, BaseCounterBuilder,
    NestedCounter, NestedCounterBuilder>(
  (state) => state.nestedCounter,
  (builder) => builder.nestedCounter,
)
  ..add(NestedCounterActionsNames.increment, _nestedIncrement)
  ..add(NestedCounterActionsNames.decrement, _nestedDecrement);
