KeyboardAvoidingView Leaves Extra Bottom Padding After Keyboard Closes

Description

Description

When using KeyboardAvoidingView with behavior="height" on Android in combination with SafeAreaView and useSafeAreaInsets(), remains even after the keyboard closes, leaving an unexpected gap at the bottom of the screen. This issue is more visible on Android devices without soft navigation buttons.

This behavior is inconsistent with iOS, where the padding collapses as expected.

Expected Behavior
When the keyboard closes, the layout should return to its original state, removing any bottom padding unless explicitly added by the developer.

Actual Behavior
After the keyboard closes on Android, an extra bottom padding remains on the screen, pushing up content unnecessarily.
Removing paddingBottom: insets.bottom fixes it, but this breaks devices with safe area (iOS or gesture nav Android) where insets are needed.

Steps to reproduce

Steps To Reproduce

1. Create a SafeAreaView wrapping a KeyboardAvoidingView (behavior="height").
2. Inside, render a FlatList and an input box pinned to the bottom.
3. Open keyboard → input shifts correctly.
4. Close keyboard → padding remains, leaving gap at bottom.

<SafeAreaView style={{flex: 1}}> <KeyboardAvoidingView behavior={Platform.OS === 'ios' ? 'padding' : 'height'} style={{ flex: 1, paddingTop: insets.top, }}> <View style={[ {flex: 1}, theme == 'dark' ? {backgroundColor: AppTheme.dark.screenBackground} : {backgroundColor: AppTheme.light.screenBackground}, ]}> </View> </KeyboardAvoidingView> </SafeAreaView>

When Keyboard is Opened it is ok
but when it is closed getting a extra padding below

从 issue 中描述的 KeyboardAvoidingView 和 SafeAreaView 复现开始，在 Android 上使用 behavior="height" 和 useSafeAreaInsets()。跟踪键盘打开和关闭时 Android 布局的变化。完成标准是：键盘关闭后底部 padding 恢复到原始状态，同时不破坏手势导航设备或 iOS 上的安全区域处理。
