quiver 3.2.2 
quiver: ^3.2.2 copied to clipboard
Quiver is a set of utility libraries for Dart that makes using many Dart libraries easier and more convenient, or adds additional functionality.
3.2.2 #
- Fix a number of doc comment issues.
 - Re-deprecate 
Optionalbut provide more nuance to the documentation. 
3.2.1 - 2022-12-20 #
- Un-deprecate 
Optional. Causing breaks with hints internally at Google. Need to remove all usages before we try to land again. 
3.2.0 - 2022-12-20 (Retracted) #
- Deprecate 
Optional. With the introduction of non-null by default in Dart SDK 2.12, existing users should migrate to non-nullable types. This type will be removed in Quiver 4.0.0. - Make 
TreeIteratornot implement deprecatedBidirectionalIterator. ThemovePreviousmethod still exists onTreeIterator. - Require Dart 2.17
 
3.1.0 - 2022-05-03 #
- Fix: Make Cache.get ifAbsent parameter nullable. The parameter was always optional; this just corrects the type.
 - Fix: Remove documentation links to the (previously removed) mirrors library.
 
3.0.1+2 - 2022-03-09 #
- Remove broken references to the defunct mirrors library.
 
3.0.1+1 - 2021-10-14 #
- Add documentation to 
Optionalsuggesting that adding new uses be avoided and existing uses should be migrated to nullable types in codebases where non-null by default has been enabled. 
3.0.1 - 2021-04-06 #
- Fix: Eliminate null check error on removal of root node of 
AVLTree. - Fix: Eliminate null check in partition internal iterator 
currentgetter. - Minor documentation typo corrections.
 
3.0.0 - 2021-02-16 #
- BREAKING CHANGE: This version requires Dart SDK 2.12.0 or later.
 - BREAKING CHANGE: Remove 
assertCheckedMode. This was deprecated in 2.1.2. Checked mode no longer exists in Dart 2.0 since the vast majority of what checked mode did is now done in the type system itself. - BREAKING CHANGE: Remove 
doWhileAsync. This was deprecated in 2.1.1. Existing callers should migrate toFuture.doWhile(). - BREAKING CHANGE: Remove IO library. This was deprecated in 2.1.4.
 - BREAKING CHANGE: Remove mirrors library. This was deprecated in 2.1.4.
 - BREAKING CHANGE: forEachAsync now returns Future
 - BREAKING CHANGE: BiMap no longer throws ArgumentError on insertion of a null key or value, if the corresponding K or V type is nullable. As before, values in the map must be unique and ArgumentError is thrown on attempts to add a key-value pair whose value is already in the map.
 - BREAKING CHANGE: 
TreeSet.firstandTreeSet.lastnow throw StateError if no element exists, as specified by the Set API contract both with null safety enabled or disabled. - BREAKING CHANGE: 
TreeSetiterators now throw ifIterator.currentis called beforemoveNextis called, or aftermoveNexthas returned false when running with null safety enabled. - Deprecate 
checkNotNull. Users of this function should migrate toArgumentError.checkNotNull. This will be removed in 4.0.0. - Deprecate 
firstNonNull. Users of this function should migrate tovar v = o1 ?? o2 ?? o3 ?? o4; ArgumentError.checkNotNull(v);. This will be removed in 4.0.0 - Eliminate dependency on package:meta.
 
2.1.5 - 2020-11-05 #
- Deprecate 
forEachAsync,reduceAsync. Existing callers should migrate toFuture.forEach. Migration examples have been added to the documentation for these methods. This will be removed in Quiver 3.0.0. 
2.1.4+1 - 2020-10-26 #
- Fix: Add dart:async import to async/string.dart. Stream wasn't exported from dart:core until Dart 2.1 but Quiver supports back to Dart 2.0.
 
2.1.4 - 2020-10-26 #
- Move 
stringFromByteStreamfrom the IO library to the async library. The original in IO has been deprecated and will be removed in 3.0.0. Users should update their code to import this function fromquiver/async.dart. If bothquiver/io.dartandquiver.async.dartare imported in the same file, users should hide the symbol from IO as described here: https://dart.dev/guides/language/language-tour#importing-only-part-of-a-library - Deprecate 
getFullPath. Users should useFile(path).resolveSymbolicLinksSync. This will be removed in 3.0.0. - Deprecate 
visitDirectory. This will be removed in 3.0.0. The source can be copied under the terms of the Apache 2.0 license. - Deprecate mirrors library. This will be removed in 3.0.0. This library was written prior to Dart 1.0 and in the interim, mirrors have been found to be problematic for production code. The primary Dart runtimes today are Flutter and the web. Flutter disables dart:mirrors altogether. On the web, the use of mirrors disables tree-shaking since in theory almost any symbol could be used reflectively; this can't be solved through static analysis -- one could imagine the situation where a user of a web app inputs the name of a method to be reflectively invoked at runtime. Users of this code can rewrite this code, or copy it into their own projects under the terms of the Apache 2.0 license.
 - Fix: Eliminate a set literal inadvertently introduced in https://github.com/google/quiver-dart/pull/359. Set literals are only supported starting in Dart 2.2, but Quiver supports back to Dart 2.0.
 - Switched from using part/part of to re-exporting the underlying libraries. We weren't making use of private symbols across files within lib/src. This improves readability by keeping imports with the code that's using them. It also allows for cross-imports within lib/src if necessary.
 
2.1.3 - 2020-02-28 #
- Fix: revert const constructor change to 
Optional.transform,Optional.transformNullwhich causes type errors when used in combination with certain operations that trigger an implicit type check. The error in question was introduced in 2.1.2. 
2.1.2+1 - 2019-11-05 #
- Minor linter fix: added curly brackets on flow-control structures to make Pana package scoring happier.
 
2.1.2 - 2019-11-05 #
- Deprecate 
assertCheckedMode. Checked mode no longer exists in Dart 2.0 since the vast majority of what checked mode did is now done in the type system itself. This will be removed in Quiver 3.0.0. - TreeSet.isEmpty/isNotEmpty are now constant-time checks.
 - Large amounts of linter-related cleanups.
 
2.1.1 - 2019-11-03 #
- Deprecate 
doWhileAsync. Existing callers should migrate toFuture.doWhile()fromdart:async. This will be removed in Quiver 3.0.0. - Fix: Eliminate a crash in 
LruMap.putIfAbsentwhenmaximumSizeis 1. - Add return types on any function that didn't include one.
 
2.1.0 - 2019-10-28 #
- Upgraded matcher dependency lower-bound from 0.10.0 to 0.12.5 to migrate from
isInstanceOftoisAin tests. - Style cleanups.
 
2.0.5 - 2019-08-06 #
- Added 
isNotBlankto strings library. 
2.0.4 - 2019-08-01 #
- Added 
FakeAsync.pendingTimersDebugInfo. 
2.0.3 - 2019-04-11 #

ifAbsentcalls inMapCache. 
2.0.2 - 2019-03-19 #
partitionis now a generic function.- New: Optional now includes an 
isNotPresentgetter alongside the existingisPresentgetter. 
2.0.1 - 2018-10-22 #
- New: Optional now includes 
transformNullableto pass maybe present values through a transformer with a nullable return value. 
2.0.0+1 - 2017-07-18 #
- Updated Dart SDK constraint to >=2.0.0-dev.61 < 3.0.0.
 
2.0.0 - 2018-07-18 #
- BREAKING CHANGE: This version requires Dart SDK 2.0.0-dev.61 or later.
 
1.0.0 - 2018-07-18 #
- BREAKING CHANGE: StreamBuffer has been changed from implementing
StreamConsumer<T>toStreamConsumer<List<T>>. Users ofStreamBuffer<List<T>>can simply change declarations toStreamBuffer<T>. In cases where the generic type is already not a list type, inputs to the list may need to be wrapped in a list. 
0.29.0+1 - 2018-03-29 #
- BREAKING CHANGE: This version requires Dart SDK 2.0.0-dev.30 or later. Bugfixes will be backported to the 0.28.x series for Dart 1 users.

addEntries,get entries,map,removeWhere,update, andupdateAll. - New: DelegatingIterable now includes a real implementation of 
followedBy, and accepts theorElseparameter onsingleWhere. - New: DelegatingList now includes real implementations of 
operator +,indexWhere, andlastIndexWhere. - New: LruMap now includes a real implementation of

Multimap.asMap()now includes real implementations ofget entriesandremoveWhere. This class also has "real" implementations ofaddEntries,map,update, andupdateAll, which just throw anUnsupportedError, as inserts and updates are not allowed on map views. - New: The list keys of 
ListMultimapnow include real implementations ofoperator +,indexWhere, andlastIndexWhere. - New: The iterable keys of 
ListMultimapandSetMultimapnow include a real implementation offollowedBy, and accept theorElseparameter onsingleWhere.

0.27.0 - 2018-01-03 #
- BREAKING CHANGE: all classes that implement 
Iterable,List,Map,Queue,Set, orTimernow implement stubs of upcoming Dart 2.0 methods. Any class that reimplements these classes also needs new method implementations. The classes with these breaking changes include:HashBiMap,DelegatingIterable,DelegatingList,DelegatingMap,DelegatingQueue,DelegatingSet,LinkedLruHashMap,TreeSet, andAvlTreeSet. - Fix: Use FIFO ordering in 
FakeAsync. PR #265 
0.26.2 - 2017-11-16 #
