Answer 1

这可能不是Firebase的问题，而是显示数据的问题，特别是偏移量映射的问题。你使用某种视觉变换吗？https://developer.android.com/reference/kotlin/androidx/compose/ui/text/input/VisualTransformation

(我宁愿把这个写在评论中，但我现在还不能发表评论)

Answer 2

我们通过使用可视化转换编写1.1.1和TextField定期接收这些崩溃日志。问题是在用户长时间按压输入后，从VisualTransformation.None到我们的自定义的视觉转换的动态变化。因为我们在onFocusEvent中更改了这一点，如果是FocusState.isFocused == true，那么竞争条件就会发生在TextField中的某个地方。

我们的解决方案是使用value键在remember语句中更改初始值更改时的视觉转换。

val ourCustomTransformation = remember {
    OurCustomTransformation()
}

var visualTransformation by remember(value) {
    mutableStateOf(
        if (value.isBlank()) {
            VisualTransformation.None
        } else {
            ourCustomTransformation
        }
    )
}
