• fix: determine bloc reference changes via identical
  • Previously identityHashCode was used to determine if the bloc reference had changed to trigger a rebuild (#2482) however, it's possible for different bloc references to have the same hashCode as a result of hash collisions. The fix uses identical to determine whether the bloc reference has changed.
• docs: add inline docs to library
• docs: minor improvements to example and README
• chore: remove unneeded imports
