Answer 1

If you are using an Android emulator then localhost on the emulator is not 127.0.0.0 it is 10.0.2.2, so, on Android emulator you need to write https://10.0.2.2:8000, the https://127.0.0.1:8000 will not work on real device too. because localhost means something different on real device.

Answer 2

Replacing the string localhost with 10.0.2.2 resolved it for me, since I was running the code in the Android emulator, which is running in a VM. It's essentially a duplicate of this question.

Answer 3

to find ip is ifconfig mac / linux

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500


    this one => inet 192.168.43.57 netmask 0xffffff00 broadcast 192.168.43.255

    nd6 options=201<PERFORMNUD,DAD>
    media: autoselect
    status: active

start php

php -S 192.168.43.57:5000 index.php

than declare on future

Future<String> getIsi()async{
      final res = await new Dio().get('http://192.168.43.57:5000/lihat-isi');
      print('res.data');
      return res.data;
    }

an result is
