How to point to localhost:8000 with the Dart http package in Flutter?
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.
replace 'localhost' in your url to wifi connection ip e.g :'http://localhost:8000' => 'http://192.168.1.102:8000'.you can get your wifi ip from command prompt with cmd>ipconfig (wireless LAN adapter WI-FI.
var url = 'http://192.168.1.102:8000';Future<String> getUnits(String category) async { var response = await httpClient.get('$url/$category'); return response.body;}
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.
