#PluginReactLynxOptions.firstScreenSyncTiming property

This flag controls when MainThread (Lepus) transfers control to Background after the first screen

This flag has three options:

"immediately": Transfer immediately

"jsReady": Transfer when background (JS Runtime) is ready

"manual": Transfer when the business calls the markFirstScreenSyncReady() API exported by @lynx-js/react, so the handover timing is fully controlled by the user

After handing over control, MainThread (Lepus) runtime can no longer respond to data updates, and data updates will be forwarded to background (JS Runtime) and processed __asynchronously__

Signature:

firstScreenSyncTiming?: 'immediately' | 'jsReady' | 'manual';

#Default Value

"immediately"
