[Question] how it is working after phone reboot (iOS)

[fvisticot]

I try to develop the same kind of background plugin for Bluetooth.

• When the phone restart, the didFinishLaunchingWithOptions is triggered with the UIApplicationLaunchOptionsBluetoothCentralsKey launch option
• I restart the BleService (as you are making for the geofence service
• once the BleService has been restarted, I notify the "dart side" of the plugin
• The plugin isolate callback is triggered
• From the callback I try to call the final SendPort send = IsolateNameServer.lookupPortByName('ble_send_port');
• The send value is null. As it is null I can not update the application state.

Is it normal that IsolateNameServer.lookupPortByName returns null after phone reboot ? Any advice ?

After more investigation, the call to IsolateNameServer.registerPortWithName was made to late in the app. It is working now.
