当我们导入依赖后,第一步需要在main.dart入口文件中把原来的MaterialApp换成GetMaterialApp作为顶层,如下所示: import'package:flutter/material.dart';import'package:get/get.dart';voidmain() { runApp(MyApp()); }classMyAppextendsStatelessWidget{@overrideWidget build(BuildContext context) {returnGetMaterialApp(...
原因是因为设置了: returnGetMaterialApp(title:'Flutter Demo',debugShowCheckedModeBanner:false,unknownRoute:MyRoutePages.notFoundRoute,theme:ThemeData(colorScheme:ColorScheme.fromSeed(seedColor:Colors.deepPurple),useMaterial3:true,),home:constMyHomePage(),getPages:MyRoutePages.routes,defaultTransition:Transiti...
第二步:调用snackbar 我们可以通过Get.snackbar() 来显示 snackbar ,如下所示 import'package:flutter/material.dart';import'package:get/get.dart';voidmain(){runApp(MyApp());}classMyAppextendsStatelessWidget{@overrideWidgetbuild(BuildContextcontext){returnGetMaterialApp(title:"GetX",home:Scaffold(appBar:Ap...
init(appRunner: (observer) async {// 确保去掉原有的WidgetsFlutterBinding.ensureInitialized() ,以免出现重复初始化绑定的异常造成无法正常初始化,// SDK内部已通过initFlutterBinding入参带入继承的WidgetsFlutterBinding实现初始化操作// 依赖ensureInitialized()初始化的代码可在此调用 // 如 final version_info =...
runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return GetMaterialApp( title: "GetX", home: GetViewAndGetWidgetExample(), ); } } 第二步:继承自GetView并使用状态管理 import 'package:flutter/material.dart'; ...

Flutter-使用dio插件请求网络(get ,post,下载文件),引入库:dio:^2.1.13可直接运行的代码:包含了post,get下载文件import'package:flutter/material.dart';import'package:dio/dio.dart';voidmain(){runApp(newMaterialApp(title:'Containerdemo',home:newvisitN
此时在app_strings.dart中添加对l10n/intl_messages.arb的引用。6.创建locallization代理 创建localizations_delegate.dart。新建AppLocalizationsDelegate类继承LocalizationsDelegate import 'dart:async';import 'package:flutter/widgets.dart';import 'package:localization_demo/app_strings.dart';class AppLocalizations...
