flutter中使用socket导致UI卡顿?

1. 在flutter使用tcp请求服务器的时候,在listen中对tcp流进行解析,解析过程包含拆包和拼包,正常情况下都没有问题,但是当服务器推送的流过快的时候,导致UI卡死,有人有好的建议吗? 2. 代码如下: ``` Future<Socket> _connect(String ip, int port) async{ if(!isConnect()) { try { _socket = await Socket.connect(ip, port, timeout: Duration(seconds: 20),); _socket.listen(_onData, onError: _onError, onDone: _onDone); }catch(e){ if(e is SocketException){ _onTimeout(); }else{ print("error : $e"); } } } return _socket; } ``` _onData中是一些拼包拆包的业务逻辑,当tcp流包含多个业务报文的时候,onData中会循环拆分包直至拆分完成,每个包都会回调到具体的业务逻辑。。现在问题是,如果服务器发送的是base64图片的话,系统就会卡死,请问 下这个问题怎么解决?

android开发中是否可以用flutter来专门制作界面交互然后用android原生java响应事件实现功能?

就是在android studio中,不再使用原生的XML布局来写界面,而是用flutter来做界面、做页面跳转等交互。然后java类文件是否可以响应flutter的一些控件事件,并把通信结果返回给flutter? <br> **总的来说就是是否可以用flutter替代android原生XML布局,flutter管界面和交互,android原生sdk管功能实现,并能互相通信?** <br> **我要怎么做?**

flutter: import 'package:wifi_configuration/wifi_configuration.dart'; 调用这个package去扫描WiFi,扫描到的结果为空, void getConnectionState() async { var listAvailableWifi = await WifiConfiguration.getWifiList(); var listWifi = listAvailableWifi.toString(); print("get wifi list : " + listAvailableWifi.toString()); print(listWifi.contains("Nebula")); print(listAvailableWifi.length); } 结果如下 I/flutter (20369): get wifi list : [] I/flutter (20369): false I/flutter (20369): 0 I/flutter (20369): 请问是什么情况

安装flutter,运行flutter_console.bat时提示错误。

1.从官网下载flutter_windows_v1.0.0-stable.zip,然后将其解压到D:\flutter。 2.运行flutter_console.bat 提示MySQL的错误![图片说明](https://img-ask.csdn.net/upload/201812/15/1544883640_383021.png) 不知道这是什么原因? 我本地有mysql,设置了环境变量,也能登录mysql,就是在flutter console控制台报这个mysql的错误。如图: ![图片说明](https://img-ask.csdn.net/upload/201812/15/1544883964_477085.png) 然后我继续执行,flutter doctor, ![图片说明](https://img-ask.csdn.net/upload/201812/15/1544885595_295969.png) 然后我打开Android Studio 创建flutter项目,项目创建完之后也提示mysql的错误,并不能进入项目,如图 ![图片说明](https://img-ask.csdn.net/upload/201812/15/1544885356_248737.png) 因为有这个错误导致无法成功创建flutter项目 flutter_console.bat文件的内容是: ![图片说明](https://img-ask.csdn.net/upload/201812/18/1545140762_896457.png) 看bat文件也并没有用到mysql的内容

Flutter ios原生开发添加广点通开屏广告,进入flutter后无法加载插件?

想要给项目添加开屏广告,但是没有广点通的相关插件,所以只能从原生那里入手。 想法是在进入flutter界面前,添加一个开屏,开屏结束后进入flutter 根据 https://github.com/gdtmobsdk/GDTMobSDK 配置好sdk后 仿照 https://github.com/gdtmobsdk/GDTMobSDK/blob/v4.11.1/GDTMobSample-Swift/AppDelegate.swift 写了自己的AppDelegate.swift 如下 出现的问题是,能够正常显示开屏广告,显示完毕后也能进入flutter,但是flutter所有的第三方插件全部失效,报错是没有找到插件。 AppDelegate.swift ``` import UIKit import Flutter @UIApplicationMain @objc class AppDelegate: FlutterAppDelegate { var splash: GDTSplashAd! var flutterViewController: FlutterViewController? var flutterEngine : FlutterEngine?; override func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? ) -> Bool { GeneratedPluginRegistrant.register(with: self) self.flutterViewController = FlutterViewController() window = UIWindow.init(frame: UIScreen.main.bounds) let rootViewController = GDTNavigationController.init(rootViewController: self.flutterViewController!) rootViewController.navigationBar.isHidden = true rootViewController.navigationBar.isTranslucent = true window?.rootViewController = rootViewController window.makeKeyAndVisible() if UIDevice.current.userInterfaceIdiom == UIUserInterfaceIdiom.phone { splash = GDTSplashAd.init(appId: Constant.appID, placementId: Constant.placementID) splash.delegate = self as? GDTSplashAdDelegate var splashImage = UIImage(named: "SplashNormal-swift") if Util.isIphoneX() { splashImage = UIImage(named: "SplashX-swift") } else if Util.isSmallIphone() { splashImage = UIImage(named: "SplashSmall-swift") } splash.backgroundImage = splashImage splash.fetchDelay = 3 splash.loadAndShow(in: window) } return super.application(application, didFinishLaunchingWithOptions: launchOptions) } } ``` 为了方便查看贴上图片代码: ![图片说明](https://img-ask.csdn.net/upload/201912/16/1576501326_484314.png) p.s flutter正常生成的代码(未改造前的): ``` import UIKit import Flutter @UIApplicationMain @objc class AppDelegate: FlutterAppDelegate { override func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? ) -> Bool { GeneratedPluginRegistrant.register(with: self) return super.application(application, didFinishLaunchingWithOptions: launchOptions) } } ```

flutter 软键盘切换问题

flutter 在使用百度键盘的时候,TextField 设置了 keyboardType 但是没用, 在多个TextField切换的时候,软键盘的类型并不是及时的,有时候需要先关闭软键盘,再点击获取焦点才能显示正确的键盘类型。 测试了百度输入法,搜狗输入法,讯飞输入法。 百度输入法不能及时变更键盘类型,搜狗和讯飞可以。 求flutter的大佬告诉我这是为啥。咋弄~ ![图片说明](https://img-ask.csdn.net/upload/202004/10/1586509209_316095.gif)

flutter Navigator路由跳转和返回,组件会重复build

https://github.com/flutter/flutter/issues/11655 为什么页面1, push到页面2,页面1会触发build?,然后回来的时候又build了一次 这样的话,我一个listView滚了很多了,结果点到详情页又得重新滚,这到底是bug还是故意为之的

flutter app启动页时间怎么可以设置短一点

* 首次打开时,启动页时间有10多秒过后再是引导页 * 非首次打开时,有5秒启动页的时间 * ![启动页](https://img-ask.csdn.net/upload/202001/23/1579712122_353012.png) ![图片说明](https://img-ask.csdn.net/upload/202001/23/1579712174_383107.png) * 想把启动页的时间控制在2秒 * 在flutter中,或者是原生android和原生ios应该怎样设置
