How to implement TextInput without state [React-native] - reactjs

Question

I'm working on an app which the users will enter large number of records continously. App functionalities are completed but the performance is bit slow in low end mobiles. As i'm new to react native i've not much idea on this. But when i googled reagrding this issue it has been noticed that when the state changes the whole app get rerenders. So for reducing the state changes i want to know how to use TextInput without using state . Because in my TextInput by using onChangeText the state is updating in every keypress.
This is a demo snack of the project Demo
<View style={styles.fixedform}>
<View style={styles.textinputViewleft}>
<TextInput
style={styles.textinput}
ref={firstref}
label="Digit"
returnKeyType="next"
value={digit.value}
onChangeText={(text) => { setDigit({ value: text, error: '' }); if (text.length === 3) { ref.current.focus(); } }}
error={!!digit.error}
errorText={digit.error}
keyboardType="numeric"
maxLength={3}
minLength={3}/>
</View>
<View style={styles.textinputView}>
<TextInput
style={styles.textinput}
ref={ref}
label="Count"
value={count.value}
onChangeText={(text) => setCount({ value: text, error: '' })}
error={!!count.error}
errorText={count.error}
keyboardType="numeric"
maxLength={3}/>
</View>
<View style={styles.textinputView}>
<Button loading={loading} disabled={disabled} style={styles.buttonView} mode="contained" onPress={onSubmitPress}>Submit</Button>
</View>
</View>

Answer 1

Try this way, It will not rerender on text change and hold the value on key press like
<TextInput
...
value={digit.value} // remove this
onChangeText={(text) => digit.value = text };
...
/>
To clear value, try one of this
1- firstref.current.clear();
2- firstref.current.setNativeProps({ text: '' });
3- firstref.current.value = '';
