synchronized 3.5.0

Lock mechanism to prevent concurrent access to asynchronous code.

Changelog

3.5.0

• Fix ReentrantLock.canLock reporting the lock free right after a synchronous block while other calls were still queued, which let synchronizedSync run before earlier synchronized calls. In that case canLock is now false and synchronizedSync returns a Future that completes in order.
• Example: readme2 was never called and now uses canLock

3.4.2

• Add synchronized-lock agent skill (skills/), installable with dart run skills@ get

3.4.1+2

• Requires dart 3.12
• Improve documentation
• MultiLock timeout now bounds the whole acquisition (one shared budget) instead of each underlying lock
• MultiLock copies its locks at construction
• synchronizedSync asserts (in debug mode) when the computation returns a Future
• ReentrantLock.canLock throws a StateError (instead of a RangeError, or true) when called from a zone that outlived its synchronized block
• Add MultiLock.toString
