df_type 0.15.1

Simplifies type conversions, inspections, nested data access, sync/async operations and more.

Changelog

0.15.1

• update

0.15.0

• breaking: Remove DateTimeUtils, StreamUtils, and StringToDurationConverter. Moved to the new df_odd package.
• breaking: Rename extension ValueOfOnEnumExtension to ValueOfOnEnumExt.
• breaking: Waiter.add now takes a WaiterOperation<T> value object; bare-function callers should switch to addFn(fn, {id}). The Waiter constructor takes Iterable<WaiterOperation<T>>.
• breaking: letAsStringOrNull(null) returns null (previously the literal four-character string 'null').
• breaking: letOrNull<T> throws ArgumentError in every build mode when given a specific collection subtype (e.g. List<int>). Previously a debug-only assert that was stripped in release, silently returning null in production.
• breaking: letMapOrNull rejects the conversion when two source keys coerce to the same target key. Previously the second entry silently overwrote the first.
• breaking: Function.tryCall no longer absorbs Error subtypes (StackOverflowError, OutOfMemoryError, AssertionError, StateError, …). It still absorbs Exception, TypeError, and NoSuchMethodError.
• feat: Add decodeJsonbStrings — recursively decodes JSON-shaped strings inside Maps and Lists, for normalising Postgres jsonb columns. Accepts an optional maxDepth parameter (default 64) so hostile or pathological nesting cannot overflow the stack.
• feat: Add WaiterOperation<T> — immutable value-object wrapper around a deferred operation, with optional id for auditing. Cross-isolate sendable when run is a top-level or static function.
• feat: Add Waiter.addFn(fn, {id}) and Waiter.removeWhere(test).
• feat: Export isJsRuntime, jsSafeIntegerBound, vmInt64Bound, and defaultDecodeJsonbStringsMaxDepth for callers that need to branch on runtime or align with the package's safety bounds.
• fix: letIntOrNull now rejects NaN, ±Infinity, and values outside the runtime-correct safe-integer range — [-2^63, 2^63) on the Dart VM, [-2^53, 2^53] on the JS runtime (Flutter web / dart2js / dartdevc) where int is backed by a 64-bit double. Previously could throw UnsupportedError, silently saturate to int64.min/int64.max, or hand back a precision-mangled value on JS.
• fix: wait / consec* now preserves positional argument order across mixed sync/async inputs.
• fix: wait / consec* / Waiter: a buggy onError handler no longer masks the original incident. The handler's own failure is surfaced through Zone.current.handleUncaughtError, while the caller still sees the original error.
• fix: wait / consec* / Waiter: onComplete now runs on every exit path, including when onError itself throws.
• fix: wait / consec* under eagerError: true no longer leaks secondary rejections through Zone.current.handleUncaughtError — exactly one attributable failure reaches the caller.
• fix: Waiter constructor and per-call error handlers are now awaited if they return a Future, and one handler's throw no longer prevents the other from running.
• fix: letDateTimeOrNull now trims whitespace before parsing.
