Flickering issue with KeyboardAvoidingView in React Native

Question

I'm experiencing a flickering issue in my React Native app when using KeyboardAvoidingView. The problem occurs when I exit an input field, and the WaveSVG component flickers.

<View style={{ flex: 1, backgroundColor: COLORS['backgroundColor'] }}>
      <Stack.Screen options={{ headerShown: false }} />
      <KeyboardAvoidingView
        behavior={Platform.OS === 'ios' ? 'padding' : 'height'}
        style={{ flex: 1 }}
      >
        <ScrollView
          keyboardShouldPersistTaps='handled'
          contentContainerStyle={{ flex: 1 }}
        >
          <View style={{ flex: 1, marginTop: 100, margin: 20 }}>
            <Text style={SignInStyles.title}>Hi,{'\n'}sign up!</Text>
            <View style={{ flexDirection: 'column', gap: 30 }}>
              <Text style={SignInStyles.description}>Get started now!</Text>
              <Input
                placeholder='Email'
                autoCapitalize='none'
                keyboardType='email-address'
                autoComplete='email'
              />
              <Input
                placeholder='Password'
                autoCapitalize='none'
                secureTextEntry={true}
              />
              <Button style={{ alignSelf: 'stretch' }}>Sign up</Button>
            </View>
          </View>
        </ScrollView>
      </KeyboardAvoidingView>
      <WaveSVG />
    </View>

Checked the positioning and layout of the WaveSVG component within the parent View. I expected that the WaveSVG component would not flicker when I exit input fields.

I've found a solution for this issue... in the app.json file I put this

android": { 
"softwareKeyboardLayoutMode": "pan", 
} 

with this there is no flickering

Answer 2

I was experiencing a flickering issue on small Android devices when opening the keyboard. The problem occurred because I had set KeyboardAvoidingView's behavior to "height".

On Android, when behavior="height" is used, the keyboard resizes the screen dynamically, which can cause conflicts with the layout, leading to flickering. The screen height adjusts along with the keyboard, creating an unstable UI experience.

To fix this, I set the behavior to "padding" for both iOS and Android:

<KeyboardAvoidingView
        behavior={'padding'}
        style={{ flex: 1 }}
      >

This ensures that when the keyboard appears, only the necessary padding is applied instead of resizing the screen, preventing flickering and improving the overall user experience.

This solution worked perfectly for me on Android devices! 🚀
