Can't get auth token stored in flutter secure storage to headers - flutter

Question

I am making flutter app using API and I have a problem. When I want to get auth token to make request, flutter says that "Expected a value of type 'String', but got one of type '_Future'". How can I make a request with auth token without that error?
My login function, where I write the token:
loginUser() async {
final storage = new FlutterSecureStorage();
Uri uri = Uri.parse("http://127.0.0.1:8000/api/account/login");
await http
.post(uri,
headers: {"Content-Type": "application/json"},
body: jsonEncode({
"username": emailController.text,
"password": passwordController.text
}))
.then((response) async {
if (response.statusCode == 200) {
var data = json.decode(response.body);
await storage.write(key: "token", value: data["token"]);
print(data["token"]);
} else {
print(json.decode(response.body));
}
});
}
My getdata function, where i use the token:
getdata() async {
final storage = FlutterSecureStorage();
Uri uri = Uri.parse("http://127.0.0.1:8000/api/account/countries");
await http.get(uri, headers: {
"Content-Type": "application/json",
"Authorization": await storage.read(key: "token")
});
}

try this code
String token = await storage.read(key: 'token');
//make sure if there is no Bearer just token in that case just pass the token
var headers = {
'accept': 'application/json',
'Authorization': 'Bearer ${token}',
};
Uri uri = Uri.parse("http://127.0.0.1:8000/api/account/countries");
Response response = await http.get(
uri,
headers: headers
);
print (response);
