sharedBridgedModuleEnvironments property
Optional process-global cache of bridged-module environments keyed by
module URI, shared across every execution that has the same allowed-set
signature (PERF step #2). When supplied, _tryLoadBridgedModule reuses an
already-built module env instead of re-registering the ~982-class flutter
bridge surface on every run. null for legacy (empty allowed-set)
instances, which keep the per-loader _bridgedModuleEnvironments cache.
Implementation
final Map<String, Environment>? sharedBridgedModuleEnvironments;
