Get.height and Get.width are printing 0.0 on first time in release mode?


I am using Getx state management for my project. Get.width and Get.height is printing 0.0 when the widget build for the first time after refreshing the screen with setState((){}) it prints the actual value. I have declared and initialized the height and width commonly.

This is my code:

import 'package:flutter/material.dart';
import 'package:get/get.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      enableLog: true,
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    print(Get.height);
    print(Get.width);
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}

Debug Output:

Release Output:

First, it prints the value 0.0 after pressing the floating button it started to print the actual value.

How can I solve this issue? In my previous projects, it was working fine.

get: ^4.6.5

Solution

  • according to issues #2523 on github there is no way to fix for now, but you can try to use:

    MediaQuery.of(context).size.width
    MediaQuery.of(context).size.height
    

    more info about Get and MediaQuery

    but this error maybe happens when the UI has not been sized and laid out on the screen yet
