Flutter Frontend and Python web.py backend GET request not working XMLHttpRequest error

I have running a python web.py server as my backend. But when I try a GET request from a Flutter it gives me XMLHttpRequest error, but when I execute my function just as Dart it works. Just accessing my GET request via a chrome also works.

Flutter:

final String uri = "192.168.1.154:5002";

var response = await http.get(
    Uri.http(
      uri, 
      "/api/getAllSettings", 
      {}
    ), 
  ).timeout(Duration(seconds: 10));

Python:

urls = (
    '/api/getInverterStatus', 'getInverterStatus',
    '/api/getSwitchStatus', 'getSwitchStatus',
    '/api/getAllSwitchesStatus', 'getAllSwitchesStatus',
    '/api/getAllSettings', 'getAllSettings',
    '/api/saveSettings', 'saveSettings'
)

class getAllSettings:
    # eg request http://192.168.1.154:5002/api/getAllSettings
    def GET(self):
        try:
            sendData = []
            allSettings = db.getAllRows(db.SwitchSetting.table_name)
            for setting in allSettings:
                sendData.append(setting.toMap())
        except:
            sendData = "N/A"
        return sendData
