Hixie	74575775bd	Introduce an explicit Key type. ... This fixes some theoretical bugs whereby we were using hashCode to try to get unique keys for objects, but really we wanted object identity. It also lays the groundwork for a new GlobalKey concept. I tried to keep the impact on the code minimal, which is why the "Key" constructor is actually a factory that returns a StringKey. The code has this class hierarchy: ``` KeyBase | Key--------------+---------------+ | | | StringKey ObjectKey UniqueKey ``` ...where the constructors are Key and Key.stringify (StringKey), Key.fromObjectIdentity (ObjectKey), and Key.unique (UniqueKey). We could instead of factory methods use regular constructors with the following hierarchy: ``` KeyBase | LocalKey---------+---------------+ | | | Key ObjectIdentityKey UniqueKey ``` ...with constructors Key, Key.stringify, ObjectIdentityKey, and UniqueKey, but I felt that that was maybe a more confusing hierarchy. I don't have a strong opinion on this.	2015-07-22 09:14:06 -07:00
Adam Barth	de717bafe9	Images don't appears in VariableHeightScrollables ... When we build widgets during layout we weren't notifying those widgets that they were mounted. Now we notify mount status changes when exiting build phases inside layout. Fixes #176	2015-07-21 14:42:21 -07:00
