Bug: KeyboardAwareScrollView causes jerky animation when keyboard appears in v1.19.1

[artem-kliuev]

Describe the bug
The KeyboardAwareScrollView component exhibits jerky/stuttering behavior when the keyboard is shown in version 1.19.1 for view with space between layout (common case for displaying forms). The same implementation works smoothly in version 1.19.0, indicating a regression introduced in the latest patch version.

When focusing an input field wrapped in KeyboardAwareScrollView, the view animation stutters noticeably as the keyboard appears, creating a poor user experience.

Code snippet

import { Text, TextInput, View } from "react-native";
import { KeyboardAwareScrollView } from "react-native-keyboard-controller";

export default function KeyboardTestScreen() {
    return (
        <KeyboardAwareScrollView
            contentContainerStyle={{
                flex: 1,
                paddingHorizontal: 17,
                paddingTop: 18,
            }}
            showsVerticalScrollIndicator={false}
            keyboardShouldPersistTaps="handled"
        >
            <View style={{ flex: 1, justifyContent: "space-between" }}>
                <View style={{ gap: 8 }}>
                    <Text>Autofocused Input</Text>
                    <TextInput
                        autoFocus
                        style={{
                            height: 40,
                            borderColor: "gray",
                            borderWidth: 1,
                            paddingHorizontal: 8,
                        }}
                    />
                </View>

                <View
                    style={{
                        backgroundColor: "black",
                        height: 40,
                        borderRadius: 8,
                        justifyContent: "center",
                        alignItems: "center",
                    }}
                >
                    <Text style={{ color: "white" }}>Button</Text>
                </View>
            </View>
        </KeyboardAwareScrollView>
    );
}

Repo for reproducing
Just a fresh expo app with code snippet above.

To Reproduce

• Install react-native-keyboard-controller v1.19.1
• Implement a KeyboardAwareScrollView with input fields while having buttons in the bottom
• Focus on any input field to trigger the keyboard
• Observe the jerky animation as the keyboard appears

Expected behavior
The view should animate smoothly when the keyboard appears, matching the behavior observed in version 1.19.0.

@artem-kliuev you are referring to this issue, right?

That button is above the keyboard, but in the end of animation it returns to its original position? Issue present only on screens with Modal?

[artem-kliuev]

@kirillzyusko Yep, that’s correct. Sorry, I forgot to mention that the issue is only reproducible in modals.

@artem-kliuev it looks like issue has been fixed in 1.19.2? Could you please re-test it? 🙏

1.19.1	1.19.2
