How do you handle API calls in Flutter?

 Use the http or dio package.

Example using http:

final response = await http.get(Uri.parse('https://api.example.com/data'));
if (response.statusCode == 200) {
  var data = jsonDecode(response.body);
}

Example using Dio (with headers):

Dio dio = Dio();
Response response = await dio.post(
  'https://api.example.com/upload',
  data: {'name': 'Ankur'},
  options: Options(headers: {'Authorization': 'Bearer token'}),
);
