@xiongdi9456 If you run the Flutter example, could you please change:

await TimeMachine.initialize({rootBundle: rootBundle})

to:

await TimeMachine.initialize({'rootBundle': rootBundle})

and tell me whether that fixes your problem? (The map key is now a string)

It helped me

await TimeMachine.initialize(<String, dynamic>{'rootBundle': rootBundle});
