Refresh previous screen on goBack()
问题 I am new to React Native. How can we refresh/reload previous screen when returning to it by calling goBack() ? Lets say we have 3 screens A, B, C: A -> B -> C When we run goBack() from screen C it goes back to screen B but with old state/data. How can we refresh it? The constructor doesn't get called 2nd time. 回答1: Yes, constructor is called only for the first time and you can't call it twice. First : But you can separate the data getter/setter from the constructor and put it in a function,
