This adds a new
preloadSnap
function to the SnapController, which is automatically called for preinstalled Snaps when the client is unlocked (i.e., whenKeyringController:unlock
is emitted). It decrypts and caches the state for the Snaps, so state doesn't need to be decrypted when first interacting with the Snap.This change requires
KeyringController:unlock
to be added to the list of allowed events for theSnapController
.
