Here is the code I am working with:
const [focused, setFocused] = useState(false);
<TextInput
style={{
...styles.inputStyles,
borderColor: `${focused ? colors.darkPurple : "#b8b8b850"}`,
borderWidth: `${focused ? 3 : 1}`,
}}
placeholder="Enter Username"
placeholderTextColor={colors.lightGray}
onFocus={() => setFocused(true)}
onBlur={() => setFocused(false)}
/>
When the screen loads, the app crashes. How can I dynamically change the borderWidth?
The issue with the crash may be due to incorrect styling input. The backticks in the style are causing the specified values to be quoted twice, leading to errors. For example, the border color should be quoted once like this:
`#b8b8b850'instead of being quoted twice. Similarly, the border width should be an integer value like
`3`rather than a string.
To resolve this, adjust your code as follows:
<TextInput
style={[
styles.input_container,
borderColor: focus1 ? colors.darkPurple : "#b8b8b850",
borderWidth: focus1 ? 3 : 1,
]}
placeholder="Enter Username"
placeholderTextColor={colors.lightGray}
onFocus={() => setFocus1(true)}
onBlur={() => setFocus1(false)}
/>
borderWidth should always be a numerical value, for more information visit https://reactnative.dev/docs/view-style-props#borderwidth
To fix this, ensure you write borderWidth: focus1 ? 3 : 1
