React Native Text Input does not shrink in width after a certain amount on Web

So I have been building a Registration Page for my project, there are three InputTexts in a row, each inputtext has a flex:1 so that they fill up the screen accordingly. It works as intended on ipads, iphones and android devices but on web after shrinking the browser (like a phones width) the InputTexts just refuse to shrink any further.

I have included the screengrabs from the Browser(Current Behaviour on Web) and also from my ipad and android (Current and Intended Behaviour)

            onChangeText={props.onChangeText}
        />

        
    );
}

const styles = StyleSheet.create({
    input: {
        height: 50,
        borderBottomWidth: 3,
        borderBottomColor: colors.InputBorder,
        color: colors.text,
        flex: 1,
        outlineStyle: "none",
    },
});

export default InputFields;

**I have only created this InputFields Component because I was just testing with flex flexBasis FlexShrink and Flexgrow, none of which work. **

It looks like the TextInput component has some kind of default width. You can fix this by adding width: "100%" to your input styles

const styles = StyleSheet.create({
  input: {
    height: 50,
    borderBottomWidth: 3,
    borderBottomColor: colors.InputBorder,
    color: colors.text,
    flex: 1,
    outlineStyle: "none",
    width: "100%",
  },
});
