Hey Flutter devs! I'm excited to announce the release of Hive CE v2.11.0-pre, introducing a new interface called IsolatedHive—a safe way to use Hive across multiple isolates.

What's New:

• IsolatedHive Interface: Enables safe Hive usage across isolates by maintaining its own dedicated isolate for database operations. It utilizes an IsolateNameServer behind the scenes to locate the Hive isolate.
• Flutter Integration: Simply call IsolatedHive.initFlutter from hive_ce_flutter to automatically set things up to use Flutter's built-in IsolateNameServer.
• Generated Extensions: The latest hive_ce_generator now provides the same easy-to-use registerAdapters extension on IsolatedHive.

Why Use IsolatedHive?

You might already be using isolates without realizing it! Common Flutter scenarios benefiting from isolate-safe Hive:

• Desktop apps with multiple windows
• Background task handling (flutter_workmanager, background_fetch, etc.)
• Push notification processing

Note: Hive now prominently warns you if it detects unsafe isolate usage.

Performance Considerations:

While IsolatedHive adds overhead due to isolate communication and isn't quite as fast as regular Hive CE, it's significantly faster and leaner than Hive v4:

Operations	Hive CE Time	IsolatedHive Time	Hive CE Size	Hive v4 Time	Hive v4 Size
10	0.00 s	0.00 s	0.00 MB	0.00 s	1.00 MB
100	0.00 s	0.01 s	0.01 MB	0.01 s	1.00 MB
1000	0.02 s	0.03 s	0.11 MB	0.06 s	1.00 MB
10000	0.13 s	0.25 s	1.10 MB	0.64 s	5.00 MB
100000	1.40 s	2.64 s	10.97 MB	7.26 s	30.00 MB
1000000	19.94 s	41.50 s	109.67 MB	84.87 s	290.00 MB

Stability & Testing:

This pre-release is as stable as possible without real-world external testing—your feedback is invaluable!
