React Native TabNavigator change TabStyle to follow according to the text - react-native

Question

I am using expo v27.0, react native 0.55 and I as you can see in the picture that the tab have somewhat a fixed width like a default width from the tab navigation, and the text wrap into three lines, I want the text to be in 1 line and nowrap, and i have tried styling (flexWrap:
'nowrap', flex: 1) in TabStyle, LabelStyle in TabBarOptions, but still can't get the tab to have the width according to the text inside the tab.
I populate the text for the tabs dynamically from json using fetch, therefore all tabs will have different width according to the text. How to I make the tab to follow the width of the text ?
All answers are greatly welcomed.
Thank you in advance.

Answer 1

Solved, turns out just need to set the width to auto as follows:
tabBarOptions: {
tabStyle: {
width: 'auto'
}
}

Answer 2

You can use render label in render header and in that you can return your Text component and Text is having numberOfLines props that will be 1 and it will add ... at end of the text after one line.
Check example snippet:
_renderLabel = props => {
let preparedProps = {
style: {
fontFamily: fonts.Regular,
marginVertical: 8
},
fontType: props.focused ? "Medium" : "Light"
};
return (
<Text
{...preparedProps}
numberOfLines={1}
ref={ref => {
ref && this.props.addAppTourTarget(ref, props.route.key);
}}
>
{props.route.type === "free" && this.state.is_premium_member
? this.labels.premium
: props.route.title}
</Text>
);
};
_renderHeader = props => (
<TabBar
{...props}
bounces={true}
style={{
backgroundColor: colors.cardBlue
}}
indicatorStyle={{
backgroundColor: colors.radicalRed,
height: 1,
borderRightWidth: initialLayout.width * 0.1,
borderLeftWidth: initialLayout.width * 0.1,
borderColor: colors.cardBlue
}}
tabStyle={{
padding: 0,
borderTopColor: "transparent",
borderWidth: 0
}}
renderLabel={this._renderLabel}
/>
);
_handleIndexChange = index => this.setState({ index });
_renderScene = ({ route, focused }) => {
switch (route.key) {
case "a":
return <One {...this.props} route={route} focused={focused} />;
case "b":
return (
<Two {...this.props} isSeries={true} focused={focused} />
);
case "c":
return <Three {...this.props} route={route} focused={focused} />;
default:
return null;
}
};
