从Flutter 1.9开始：如何在浏览器中运行Flutter App？Flutter run -d chrome无法正常工作

Question

从flutter 1.9开始，flutter_web在flutter中合并。我正在尝试在chrome浏览器中运行初始flutter应用程序，但失败。操作系统是Ubuntu 19.04

我成功使用的命令：flutter upgrade

颤动创建test_1_9

cd test_1_9

扑动

该命令不起作用：

颤振运行-d铬

=>未找到名称或ID与“ chrome”匹配的设备

我尝试使用google-chrome作为设备名称，结果相同

Answer 1

https://flutter.dev/docs/get-started/web

$ flutter channel master
$ flutter upgrade
$ flutter config --enable-web

$ flutter devices  //downloads sky_engine and sdk tools then shows a list of devices including chrome

$ flutter create test_app
$ flutter run -d chrome  //local host will run chrome

Answer 2

flutter run -d chrome --web-renderer html

Answer 3

您是否启用了Web支持flutter config --enable-web？

从此链接获得参考

Answer 4

对于这些chrome甚至在之后仍无法检测到的人flutter config --enable-web。您应该检查您的颤动是否在适当的分支中，以列出所有分支，请使用：

颤振通道

输出可能如下所示：

Flutter channels:  
   beta  
   dev  
   master  
*  stable 

带星号前缀的项目表示您所在的分支。要切换到主分支，请尝试：

颤振通道主控

之后，您flutter doctor可以列出chrome设备。

Answer 5

就我而言 - flutter doctor 给了我以下输出

\n

[\xe2\x9c\x97] Chrome - develop for the web (Cannot find Chrome executable at google-chrome)\n    ! Cannot find Chrome. Try setting CHROME_EXECUTABLE to a Chrome executable.\n

\n

与 arch 一样，二进制文件称为 google-chrome-stable 和/或 google-chrome-unstable

\n

export CHROME_EXECUTABLE=/usr/bin/google-chrome-stable\n

\n

这就是让它工作所需的一切。
