flutter cannot get value from async

[gong tji]

Hello everyone,

I want to make simple validation to validate url through http package,

but it always return null if I call it on validation, here's my code :

Future<int> check_url(String val) async {    final response = await http.get("https://www.youtube.com/oembed?url=$val&format=json");    return await response.statusCode;  } int url_test(String url)  {    check_url(url).then((value) {      return value;    });  } TextFormField( decoration: InputDecoration(    hintText: 'Enter text',  ),  textAlign: TextAlign.center,  controller: test,  validator: (text) {    print(url_test(text)); //always return null    return null;  } ),

please someone help me

Thanks

final response = await http.get("https://www.youtube.com/oembed?url=$val&format=json");

Does the above line compile?  I guess http.get takes uri as argument, but you are passing a String.
