| ## 0.24.0-dev |
| |
| * Migrate to [null safety](https://dart.dev/null-safety). |
| * Update ObservableMap to notify observers about changes for all methods. |
| |
| ## 0.23.0 |
| |
| * Support latest dependencies. |
| * Reintroduce custom equality for `PropertyChangeRecord` from 0.18.0. |
| |
| ## 0.22.2 |
| |
| * Add `toObservableList` and `toObservableMap`, better typed versions of |
| `toObservable`. |
| |
| ## 0.22.1+5 |
| |
| Fix generic type error that occurs when using ChangeNotifier with a subclass of |
| ChangeRecord. Previously, calling `notifyChanges()` on |
| `class Foo with ChangeNotifier<CustomChangeRecord> {}` would throw a type error. |
| Now, the `changes` stream emits a custom `ChangeRecords` class that implements |
| the `List` interface. This change is backwards compatible. |
| |
| ## 0.22.1+4 |
| |
| * Support Dart 2 stable. |
| |
| * Bump and widen dev dependencies on build packages. |
| |
| ## 0.22.1+3 |
| |
| Update implementations of the `cast()` and the deprecated `retype()` methods. |
| * The `retype()` method on List and Map is deprecated and will be removed. |
| * The `cast()` method should do what the `retype()` method did. |
| |
| ## 0.22.1+2 |
| |
| * Widen dependency on quiver to include v0.29. |
| |
| ## 0.22.1+1 |
| |
| * Fixes for Dart2 runtime type errors. |
| |
| ## 0.22.1 |
| |
| * Added `ObservableList.castFrom`, similar to `List.castFrom`. |
| |
| * Changed `ObservableList`'s `cast` and `retype` function to create a forwarding |
| instance of `ObservableList` instead of an instance of `List`. |
| |
| ## 0.22.0 |
| |
| * Added `ObservableMap.castFrom`, similar to `Map.castFrom`. |
| |
| * Fixed a bug where `ObservableMap`'s `cast` and `retype` function would create |
| a new empty instance instead of a forwarding instance. |
| |
| ## 0.21.3 |
| |
| * Support Dart 2 collection methods where previously threw `UnimplementedError`. |
| |
| ## 0.21.2 |
| |
| * Fix `toObservable(deep: false)` to be shallow again. |
| * Remove use of `Maps`, for better compatibility with Dart 2. |
| |
| ## 0.21.1 |
| |
| * Updated one test to comply with Dart 2 voidness semantics. |
| * Fix Dart 2 runtime cast failure in `toObservable()`. |
| * Loosen `ObservableList.from()` to take `Iterable`, not `Iterable<T>`. This |
| matches `List.from()` and avoids some unnecessary cast failures. |
| |
| ## 0.21.0 |
| |
| ### Breaking Changes |
| |
| Version 0.21.0 reverts to version 0.17.0+1 with fixes to support Dart 2. |
| Versions 0.18, 0.19, and 0.20 were not used by the package authors and |
| effectively unsupported. This resolves the fork that happened at version 0.18 |
| and development can now be supported by the authors. |
| |
| #### Reverted Changes |
| |
| (From 0.20.1) |
| * Revert add `Observable<List|Set|Map>.unmodifiable` for immutable collections |
| * Revert add `Observable<List|Set|Map>.EMPTY` for empty immutable collections |
| * This can be used as an optimization for libraries that always need to return |
| an observable collection, but don't want to allocate a new instance to |
| represent an empty immutable. |
| |
| (From 0.20.0) |
| * Revert add `ObservableSet`, `SetChangeRecord`, and `SetDiffer` |
| |
| (From 0.19.0) |
| * Revert refactor and deprecate `ObservableMap`-specific API |
| * `ObservableMap` no longer emits `#keys` and `#values` change records |
| * `ObservableMap.spy` is deprecated, becomes `.delegate` instead |
| * Revert Potentially breaking: `ObservableMap` may no longer be extended |
| |
| Revert considered deprecated to be notified of `length` changes. |
| |
| (From 0.18.0) |
| * Revert refactor and deprecate `ObservableList`-specific API |
| * `ObservableList.applyChangeRecords` |
| * `ObservableList.calculateChangeRecords` |
| * `ObservableList.withLength` |
| * `ObservableList.deliverListChanges` |
| * `ObservableList.discardListChanges` |
| * `ObservableList.hasListChanges` |
| * `ObservableList.listChanges` |
| * `ObservableList.notifyListChange` |
| * Revert potentially breaking: `ObservableList` may no longer be extended |
| |
| Revert considered deprecated to be notified of `length`, `isEmpty` and |
| `isNotEmpty` `PropertyChangeRecord`s on `ObservableList` |
| |

| |
| ## 0.20.4+1 |
| |

| |
| ## 0.20.1 |
| |
| * Add `Observable<List|Set|Map>.unmodifiable` for immutable collections |
| * Add `Observable<List|Set|Map>.EMPTY` for empty immutable collections |
| * This can be used as an optimization for libraries that always |
| need to return an observable collection, but don't want to |
| allocate a new instance to represent an empty immutable. |
| |
| ## 0.20.0 |
| |
| * Add `ObservableSet`, `SetChangeRecord`, and `SetDiffer` |
| |
| ## 0.19.0 |
| |
| * Refactor and deprecate `ObservableMap`-specific API |
| * `ObservableMap` no longer emits `#keys` and `#values` change records |
| * `ObservableMap.spy` is deprecated, becomes `.delegate` instead |
| * Potentially breaking: `ObservableMap` may no longer be extended |
| |
| It is also considered deprecated to be notified of `length` changes. |
| |
| ## 0.18.1 |
| |
| * Bug fix: Do not throw when `Observable<T>.notifyChange` is used |
| |
| ## 0.18.0 |
| |
| * Refactor and deprecate `ObservableList`-specific API |
| * `ObservableList.applyChangeRecords` |
| * `ObservableList.calculateChangeRecords` |
| * `ObservableList.withLength` |

| and `isNotEmpty` `PropertyChangeRecord`s on `ObservableList` - in a |
| future release `ObservableList.changes` will be |
| `Stream<List<ListChangeRecord>>`. |
| |
| ## 0.17.0+1 |
| |
| * Revert `PropertyChangeMixin`, which does not work in dart2js |
| |
| ## 0.17.0 |
| |
| This is a larger change with a goal of no runtime changes for current |
| customers, but in the future `Observable` will [become][issue_10] a very |
| lightweight interface, i.e.: |
| |
| ```dart |
| abstract class Observable<C extends ChangeRecord> { |
| Stream<List<C>> get changes; |
| } |
| ``` |
| |
| [issue_10]: https://github.com/dart-lang/observable/issues/10 |
| |
| * Started deprecating the wide `Observable` interface |
| * `ChangeNotifier` should be used as a base class for these methods: |
| * `Observable.observed` |
| * `Observable.unobserved` |
| * `Observable.hasObservers` |
| * `Observable.deliverChanges` |
| * `Observable.notifyChange` |
| * `PropertyChangeNotifier` should be used for these methods: |
| * `Observable.notifyPropertyChange` |
| * Temporarily, `Observable` _uses_ `ChangeNotifier` |
| * Existing users of anything but `implements Observable` should |
| move to implementing or extending `ChangeNotifier`. In a |
| future release `Observable` will reduce API surface down to |
| an abstract `Stream<List<C>> get changes`. |
| * Added the `ChangeNotifier` and `PropertyChangeNotifier` classes |
| * Can be used to implement `Observable` in a generic manner |
| * Observable is now `Observable<C extends ChangeRecord>` |
| * When passing a generic type `C`, `notifyPropertyChange` is illegal |
| |
| ## 0.16.0 |
| |
| * Refactored `MapChangeRecord` |
| * Added equality and hashCode checks |
| * Added `MapChangeRecord.apply` to apply a change record |
| * Added `MapDiffer`, which implements `Differ` for a `Map` |
| |
| ## 0.15.0+2 |
| |
| * Fix a bug in `ListDiffer` that caused a `RangeError` |
| |
| ## 0.15.0+1 |
| |
| * Fix analysis errors caused via missing `/*<E>*/` syntax in `0.15.0` |
| |
| ## 0.15.0 |
| |
| * Added the `Differ` interface, as well as `EqualityDiffer` |
| * Refactored list diffing into a `ListDiffer` |
| * Added concept of `ChangeRecord.ANY` and `ChangeRecord.NONE` |
| * Low-GC ways to expression "something/nothing" changed |
| * Refactored `ListChangeRecord` |
| * Added named constructors for common use cases |
| * Added equality and hashCode checks |
| * Added `ListChangeRecord.apply` to apply a change record |
| * Added missing `@override` annotations to satisfy `annotate_overrides` |
| |
| ## 0.14.0+1 |
| |
| * Add a missing dependency on `pkg/meta`. |
