        <Text
             adjustsFontSizeToFit
            style={styles.headerText}>??</Text>
    </View>
 ),
  tabBarIcon: ({ focused, tintColor }) => (
  <Image
      source={focused ? require('../images/clickmessage.png') : 
      require('../images/message.png')}
      style={{ width: 26, height: 26, tintColor: tintColor }}
  />
),
headerLeft: ({ focused, tinColor }) => {
    <Image
        source={focused ? require('../images/clickmessage.png') : 
        require('../images/message.png')}
        style={{ width: 26, height: 26, tintColor: tintColor }}
     />
 }
 };
render() {
    return (
        <View style={styles.container}>
        <MessageContent /> …
