Is there a way to retrieve the language of a phone with Flutter so that the application can detect t-CodePudding

I want to change the language of my flutter application by retrieving the default language of the phones set in the preferences. How to do ?

CodePudding user response：

In MaterialApp you can set application language with local property, local property by default is system language

if you don't set a custom local, app will use system language if this language is available in your app

CodePudding user response：

Yes you can retreive that on the start of the application using localeResolutionCallback in the MaterialApp

MaterialApp(
                  title: 'SportsTak',
                  home:Home(),
                  localeListResolutionCallback: ( localeOfDevice, listedLocales){
        
                  //Here is what you can loop through listedLocales and compare from localeOfDevice and return the locale you support
                    
                  },
                  supportedLocales:[ ] , //listofsupportedlocales
                );

Yes, you may use Platform.localeName from dart:io to get the name of the current device locale.

import 'dart:io';

String languageCode = Platform.localeName;
