Hi
I want to run function inside View tag , is there anyway to do so ?

checkUser = () => {
};

render() {

return (

   <View>
    {this.checkUser()}
  </View>
);

}

Yes you are doing it right, just make sure you return jsx from your checkUser function though. like;

checkUser = () => {
return (
<Text> Example Text </Text>
)
}

If you just want to return a string from checkUser, you will need to put the call to {this.checkUser()} between <Text></Text> tags:

checkUser = () => {
  if (userIsValid()) {
    return "User is valid!";
  } else {
    return "Invalid user!";
  }
};

render() {
  return (
    <View>
      <Text>
        {this.checkUser()}
      </Text>
    </View>
  );
}
