Description
Description
Setting color in style prop for an uncontrolled input based on focus clears the TextInput's value.
example:
...
<TextInput
onBlur={onBlur}
onFocus={onFocus}
placeholder={placeholder}
style={[
{
color: isFocused ? "#f00" : "#000",
},
]}
/>
...
isFocused is set based on onBlur and onFocus.
This same issue is not noticed for a controlled input. I have also linked a repro link with both cases side by side.
Affected platform: Android
Steps to reproduce
- Run the application with
npx react-native run-android - Interact with controlled input (notice normal behaviour)
- Interact with uncontrolled input, notice value of input disappearing when you blur the focus

Research direction
Start with the linked reproducer and run it with npx react-native run-android on React Native 0.73.5. Compare the controlled and uncontrolled TextInput cases while changing the focus-based color; done means the uncontrolled input retains its value after blur and the controlled case remains unaffected.
