flutter – Cannot get any response from HTTP API – Stack Overflow

I searched tutorials and library documentations which I already followed the sample codes using either Dio or Http. However, I don’t know why I cannot get a response from calling the api. There is no error and any message allows me to debug. I read the logging from cloudwatch for the api gateway. There is no trigger. The app cannot be processed any more after calling the api as I use await for waiting for the response. How should I fix it?

  Future makeGetRequest() async {
    try {
      const url="https://918pynqzta.execute-api.ap-southeast-1.amazonaws.com/dev/getAllElderly";

      final uri = Uri.parse(url);

      final response = await http.get(uri);
      print(response);
    } catch (e) {
      print('Error: $e');
    }
  }

ElevatedButton(
                        onPressed: () async {
                          await makeGetRequest();
                        },)
