How I use get method with variables in flutter http?

Question

I want to call API but I can't give latitude and longitude as variables.

Answer 1

basically you would want to define your uri in the getData method. example:

getData({String latitude,String longitude})async{
..define uri. var url =Uri.https..
http.Response..

Answer 2

As griffin said to write url in getData function, so do that and also Extract and pass the query parameters like this in that function

void getData(double latitude,double longitude) async {
    Map<String, dynamic> param = {
          'longitude': longitude,
          'latitude': latitude,
        };

    var url = Uri.https('api/openweathermap.org',
        '/data/2.5/weather',
        param);
    
    }

Answer 3

Create a function instead of variable

Uri url(double latitude, double longitude) {
    return Uri.https('api.abc.org', 'data/123/abc', {
      'lat': latitude,
      'lon': longitude,
    });
  }

Future<void> getData(double latitude, double longitude) async {
  final response = await http.get(url(latitude, longitude));
}
