ac_dart_essentials

Added

• IsolateErrorListener record typedef: ({SendPort sendPort, void Function() close})
• JsonObjectArray typedef (List<JsonObject>)
• Top-level durationMin, durationMax, durationAdd, durationSubtract, durationLt, durationLte, durationGt, durationGte, durationEqual functions
• Top-level castAsJsonObjectArray and jsonGet functions
• PatternExtensions.captureGroup([String? name]) — replaces removed namedCapture
• platform_independent.dart export file (corrects the platform_independant.dart spelling)
• Inspect constructor is now const
• Memoizer.value now throws StateError when accessed before runOnce

Changed

• createIsolateErrorListener now returns IsolateErrorListener instead of SendPort; use .sendPort to pass to Isolate.addErrorListener and call .close() when the isolate exits
• StringPointer.operator+ / operator- now return a new StringPointer instance instead of mutating _offset; use pointer.offset += n to advance in place
• JsonNumber changed from double to num — correctly handles integer JSON numbers decoded by dart:convert
• UriQueryParameters changed from Map<String, dynamic> to Map<String, Object>
• DurationUtil static methods moved to top-level duration* functions; class retained as @Deprecated forwarding shim
• JsonUtil.castAsCollection / JsonUtil.get moved to top-level castAsJsonObjectArray / jsonGet; class retained as @Deprecated forwarding shim
• ConverterPassthroughSink changed from extends Sink<S> to implements Sink<S>
• SDK minimum constraint raised from >=2.19.5 to >=3.0.0

Deprecated

• JsonCollection — use JsonObjectArray instead
• DurationUtil class — use the top-level duration* functions instead
• JsonUtil class — use castAsJsonObjectArray / jsonGet instead

Removed

• PatternExtensions.namedCapture — use captureGroup instead
• platform_independant.dart export file (misspelling; replaced by platform_independent.dart)

Fixed

• CaseStringExtension.toTitleCase() — no longer throws RangeError on empty strings
• truncate — now throws ArgumentError for negative maxLength (was a stripped assert)
• PatternExtensions.entireMatch / entireMatchI — now correctly handles RegExp inputs by extracting .pattern; previously used toString() which produced malformed regex literals
• PatternTrimStringExtension.patternTrimLeft / patternTrimRight — same RegExp source fix
• Inspect._inspectValue — uses take(n+1).length > n instead of .length to avoid O(n) evaluation of lazy Iterables
• DataHistorySink.add — window eviction condition corrected from > to >=; was keeping one extra element when the buffer was exactly at window size
