Flutter 3.0实现Windows本地化/国际化

参照 Flutter 2.8.1本地化/国际化应用程序名称 可以实现 Android/macOS/iOS/Web 的应用名称相关的国际化。Linux 参考 Flutter 3.0实现Linux本地化/国际化。

那么在 Windows 应用上如何相同的功能呢？

下面我们探讨一下一个比较简单的解决方案，就是直接修改RC文件，这个方案 适用于涉及到的语言类型不太多的情况。

Windows 代码编译，需要安装 Microsoft Visual Studio 2022 Community，但是不能直接使用 Microsoft Visual Studio 2022 Community 编辑 RC 文件，打开就会报错：

fatal error RC1015: cannot open include flie 'winres.h'

1	fatal error RC1015: cannot open include flie 'winres.h'

具体的操作方法如下：

我们假定工程的名字为 LanauageTest

首先在项目根目录下，执行

$ flutter build windows

1	$ flutter build windows

生成 build 目录，然后使用 Microsoft Visual Studio 2022 Community 打开 build\windows\LanauageTest.sln 文件。

接着在资源视图中找到字符串资源（如果不存在则新建），选择默认的 StringTable ，然后右键选择 “插入副本”

虽然可以使用上面的操作来添加语言，但是只能作为参考，原因在于 Microsoft Visual Studio 2022 Community的 RC 文件编辑器在修改 LanauageTest.RC 文件的时候，把预定义的宏进行了展开，直接使用宏的实际值替代了宏本身，导致这些数据失去动态变化的能力。我们只能手工再编辑一次，恢复原来的宏才可以。

至于使用的话，可以通过 LoadString 加载定义的字符串资源，更详细参考 Using Resources。

Windows 10系统VirtualBox无法进入系统，日志报错“HM: HMR3Init: Attempting fall back to NEM: VT-x is not available”

在Windows 10上使用 Linux 子系统的时候，无法成功启用。根据官方文档旧版 WSL 的手动安装步骤之后，依旧没效果，反倒是VirtualBox无法进入系统了。

观察日志，报错信息如下：

Intel CPU

{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

1 2	{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available {timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

AMD CPU

{timestamp} HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

1 2	{timestamp} HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available {timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

解决方案如下：

1.使用管理员启动命令行.

2. 执行如下命令:

bcdedit /set hypervisorlaunchtype off

1	bcdedit /set hypervisorlaunchtype off

某些电脑需要额外执行如下命令:

DISM /Online /Disable-Feature:Microsoft-Hyper-V

1	DISM /Online /Disable-Feature:Microsoft-Hyper-V

3. 重启电脑

GTX760支持4k分辨率吗?

支持的，所有开普勒架构的桌面显卡，都可以支持到4K分辨率的输出，包括GTX650等极端开普勒架构显卡。

以下是GTX760最新的官方参数：

从技术支持和特性描述可以看出，GTX760原生支持4K输出，当然也就包括了各个子生厂商生产出的各种GTX760。并且可以通过DP接口输出4K@60Hz，通过HDMI输出4K@24Hz~30Hz，HDMI下的刷新率不如DP是因为HDMI的版本带来的带宽问题，所以如果你连接的是60Hz刷新率的4K显示器，那么建议是用DP接口进行连接。

之所以一些品牌的GTX760没写支持4K，是因为在GTX760发布的时候，4K还并不盛行，所以一些产品的资料里就并没注明支持4K，后来这些资料也并未进行更新，所以可能会产生误导，实际上是支持的。

只是GTX760的4K游戏性能较弱，如果你打算用GTX760在4K下进行游戏，那么可能需要调低不少特效，才能保证一定的画面流畅度。

Flutter构建Windows应用

从2.10之后的版本，flutter已经正式支持构建Windows应用。不过距离实现全平台构建，还需要考虑很多问题，flutter构建的应用更加适合移动端的使用习惯，如果需要构建Windows应用，我的建议是使用一些适合桌面端的widget。

具体方法如下：

条件

需要安装Visual Studio 2019或者Visual Studio 2022，简言之，需要安装Windows 10 SDK。
2.10之前的版本是默认关闭的。Linux和Mac是默认关闭的，可以手动进行打开。

方法

1. 打开Windows的平台支持

PowerShell输入如下指令（如下命令可以使用flutter config查看，2.10以上的版本默认开启）

flutter config --enable-windows-desktop

# 其他平台
flutter config --[no-]enable-macos-desktop

flutter config --[no-]enable-linux-desktop

flutter config --enable-windows-desktop

# 其他平台

flutter config --[no-]enable-macos-desktop

flutter config --[no-]enable-linux-desktop

可以使用flutter doctor查看情况

则需要更新Flutter SDK到3.0.2以上的版本即可，如下：

$ flutter upgrade

1	$ flutter upgrade

具体原因，参考：[windows] Exception: Bad UTF-8 encoding when running flutter doctor or building/running for Windows #102451

2. 在旧项目中添加Windows平台支持

在项目地址输入如下指令

flutter create --platforms=windows[,macos,linux] .

1	flutter create --platforms=windows[,macos,linux] .

注意: 项目的名称必须是全小写，如果出现大小写则会报错

解决：

前提：在排除没有配置公钥的情况下。

在Git的安装目录下 Git > etc > ssh 文件夹下找到 ssh_config 文件
在文件末尾添加一下代码（注意，这里的 xxx.com 就是远程仓库地址或者ip，格式如：baidu.com）

Host xxx.com
    HostkeyAlgorithms +ssh-rsa
    PubkeyAcceptedAlgorithms +ssh-rsa

Host xxx.com

HostkeyAlgorithms +ssh-rsa

WOL网络唤醒在微星主板上开启(ubuntu 20.04/Windows 10双系统)

网络唤醒

微星H97I-AC的板子开启WOL网络唤醒

主板：微星 H97I-AC，集成 Realtek 千兆网卡,这个网卡自带网络唤醒功能，但是需要在操作系统中通过驱动开启这个功能，BIOS中无法直接开启。
操作系统：Windows 10/ubuntu 20.04双系统，双系统都需要进行配置，才能实现全部系统关机之后都能正常唤醒。

BIOS 设置

高级–整合周边设备–网卡ROM启动，设置为允许
高级–电源管理设置–Eup 2013，设置为禁止
高级–唤醒事件设置–PCIE设备唤醒，设置为允许

Windows 10 设置

控制面板–所有控制面板项–网络连接
在网卡适配器点击鼠标右键–属性，弹出的属性对话框中
选择网络选项卡–配置
选择高级选项卡，将关机网络唤醒设置为开启，将魔术封包唤醒设置为开启
电源管理选项卡，勾选下面三个选项，允许此设备唤醒计算机。

ubuntu 20.04设置

$ sudo apt-get install ethtool

$ sudo apt-get install vim

$ sudo vim /etc/systemd/system/wol.service

$ sudo apt-get install ethtool

$ sudo apt-get install vim

$ sudo vim /etc/systemd/system/wol.service

里面的内容如下：

[Unit]
Description=Configure Wake On LAN

[Service]
Type=oneshot
ExecStart=/sbin/ethtool -s eth0 wol g

# 如果有多张网卡
# ExecStart=/bin/bash -c '/sbin/ethtool -s enp5s0 wol g && /sbin/ethtool -s eth0 wol g'


[Install]

[Install]

上述配置是向驱动发送控制命令，启用网络唤醒功能。

启用服务

$ sudo systemctl daemon-reload

$ sudo systemctl enable wol.service

$ sudo systemctl start wol.service

$ sudo systemctl daemon-reload

$ sudo systemctl enable wol.service

$ sudo systemctl start wol.service

远程唤醒

$ sudo apt-get install wakeonlan -y

$ wakeonlan MAC

$ sudo apt-get install wakeonlan -y

$ wakeonlan MAC

也可尝试 etherwake

$ sudo apt-get install etherwake -y

$ etherwake MAC

# OpenWrt
# opkg install etherwake
# /usr/bin/etherwake -i br-lan MAC

$ sudo apt-get install etherwake -y

$ etherwake MAC

# OpenWrt

# opkg install etherwake
