问题 I need to create a login form. After user successfully login than I need to start some kind of timer (ex: 3 min), so if user has no reaction to app or other word if flutter app state is paused, suspended or inactive more than 3 min. the app will goto main login page. As long as user has interaction with app I need to cancel the timer and only I need to star timer app state is paused, suspended or inactive. How do I do that? I try to implement the "WidgetsBindingObserver" but its look like is

Conditional Timeout

一个人想着一个人 提交于 2021-02-16 21:07:45
问题 I have some code, there are 3 timers, GracefulExecutionTimeout - total running time WaitTimeout - time to initial wait for first message IdleTimeout - time to wait for subsequent messages If any of the timers are reached the app should cleanly exit. I have it working below msgs := make(chan string) go func() { time.Sleep(time.Second) msgs <- "test" }() // graceful max execution time gracefulMaxTimeout := time.Second * time.Duration(10) gracefulMaxTimer := time.NewTimer(gracefulMaxTimeout) //

问题 (How) can I activate a periodic timer interrupt in Python?
