MpStore class

In-memory state store for one active mini-program host instance.

Values are intentionally memory-only. Persistent data belongs in a future storage layer, while private data should remain behind publisher APIs.

Replaces key with value.

toBindingData() → Map<String, dynamic>

Returns a defensive copy of the state namespace for binding resolution.

toString() → String

A string representation of this object.

inherited

updatePolicy(MiniProgramLiveStatePolicy policy) → void
