I have a statfull class called 'Location' which get the location with Geolocatar and Im showing the location with this :

 Text(currentPosition!=null? '$currentPosition' : '----',),

and this is :

static Position? currentPosition;

and I have another class called 'WeatherApi' which Im using Openweathermap Api to get the weather . now I want to use the currentPosition in the api url

https://api.openweathermap.org/data/2.5/weather?lat=44.34&lon=10.99&appid={API key}

how can I use the currentPosition in the url? I have tried widget.variablename but didn't work

CodePudding user response：

You can pass the location details through the constructor of Location class.

Check out this for more info

CodePudding user response：

You can define a global variable outside the 'Location' widget as a 'currentPosition',

class Position {
  static String? currentPosition;
}

call from 'Location' this variable and set it.

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    Position.currentPosition = 'currentPosition';
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: TextButton(
          onPressed: () {
            Navigator.of(context).push(
              MaterialPageRoute(
                builder: ((context) => LocationWidget()),
              ),
            );
          },
          child: Text('Click Me'),
        ),
      ),
    );
  }
}

Then call it again from 'WeatherApi' and use it.

class WeatherWidget extends StatefulWidget {
  const WeatherWidget({super.key});

  @override
  State<WeatherWidget> createState() => _WeatherWidgetState();
}

class _WeatherWidgetState extends State<WeatherWidget> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Text(Position.currentPosition ?? 'null'),
      ),
    );
  }
}
