scopePrefix property
Scope: which registry ids belong to this controller's screen.
Screens mounted at once (tabs, split-view) share
HintTargetRegistry.defaultInstance: without a scope a controller sees
foreign ids — a step can activate on another screen's target, and typo
candidates can false-fire. One controller per screen with ids prefixed
per screen (scopePrefix: 'greenhouse-' / 'spread-'); null — no
scoping (global).
Implementation
final String? scopePrefix;
