Flutter- estructura de una llamada a API -GET

Tiempo de lectura: < 1 minuto

La estructura para realizar una llamada desde flutter a una api y obtener datos es de la siguiente manera:

primero declaramos e inicializamos una variable con la ruta a la api, en este caso la llamo uri:

final uri = 'https://nombre/ruta/api';

Depués declaro las cabeceras, tipo-contenido

final headers = {
      'Content-Type': 'application/json',
  };

A continuación genero la llamada y guardo la respuesta en una variable a la que he llamado response.

final response = await http.get(Uri.parse(uri), headers: headers);

Para saber si la llámada se realizado correctamente, compruebo el statusCode e imprimo por consola en modelo json la respuesta de datos con la siguiente línea de código.

if (response.statusCode == 200) {

      print(json.decode(response.body));
  
} else {
      print('Error en la solicitud: ${response.statusCode}');

}

El código completo de la llamada GET lo muestro a continuación:

  Future<void> getApi() async {
    final uri = 'https://nombre/ruta/api';
    final headers = {
      'Content-Type': 'application/json',
    };
    final response = await http.get(Uri.parse(uri), headers: headers);
    if (response.statusCode == 200) {

      print(json.decode(response.body));

    } else {
      print('Error en la solicitud: ${response.statusCode}');

    }
  }

Espero que les sirva de ayuda !! Les deseo un feliz día.
