flutter签名,flutter手写签名

新建一个flutter项目，可以在ios上运行，四步搞定！

1. 建立一个flutter项目的命令

2. 在ios文件夹下，生成pods文件夹

3. Xcode环境签名设置；

把错误的版本删除再添加，可解决签名错误问题；必须先删除再添加，直接修改可能不起作用。团队开发，必须使用团队的签名。

4.运行创建的flutter项目；

选择真机、模拟机，点击运行按钮，或使用命令运行：

下面两步是赠送的：

5.新加一款插件，所涉及的命令；

ios 端所涉及的命令

6. 刚更新的插件和已有的插件有冲突怎么办？

可以试一试以下步骤：

相关问答

Q1: Flutter真机调试之后，安装新版本时提示:更新包与已安装应用签名不一致

需要在命令行操作

但是我查出来的并没有我的包名

6.成功了，现在在安装APP，就ok了

夏天的飞鸟，飞到我的窗前唱歌，又飞去了。

秋天的黄叶，它们没有什么可唱，只叹息一声，飞落在那里。

stray birds of summer come to my window to sing and fly away.

and yellow leaves of autumn, which have no songs, flutter and fall

there with a sign.

2

世界上的一队小小的漂泊者呀，请留下你们的足印在我的文字里。

o troupe of little vagrants of the world, leave your footprints in my words.

3

世界对着它的爱人，把它浩翰的面具揭下了。

它变小了，小如一首歌，小如一回永恒的接吻。

the world puts off its mask of vastness to its lover.

it becomes small as one song, as one kiss of the eternal.

4

是大地的泪点，使她的微笑保持着青春不谢。

it is the tears of the earth that keep here smiles in bloom.

4． 生命中，不断地有人进入或离开。于是，看见的，看不见了；记住的，遗忘了。生命中，不断地有得到和失落。于是，看不见的，看见了；遗忘的，记住了。然而，看不见的，是不是就等于不存在？记住的，是不是永远不会消失？

There is someone that is coming or passing away in your life around the clock, so you may lose sight of those seen, and forget those remembered. There is gain and loss in your life, so you may catch sight of those unseen, and remember those forgotten. Nevertheless, doesn’t the unseen exist for sure? Will the remembered remain forever?

5． 后悔是一种耗费精神的情绪。后悔是比损失更大的损失，比错误更大的错误。所以不要后悔。

Penitence is something that enervates our spirit, causing a greater loss than the loss itself and making a bigger mistake than the mistake itself. So never regret.

Q3: flutter 签名和获取应用签名

签名：

    keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

    【~/key.jks】生成文件的路径和文件名

keytool -importkeystore -srckeystore C:/test/key.jks -destkeystore C:/test/key.jks -deststoretype pkcs12

迁移到行业标准格式 PKCS12

在project/android下创建key.properties文件

文件内容

在Projects\android\app\build.gradle里的 android{ 上边添加

def keystorePropertiesFile = rootProject.file("key.properties")

def keystoreProperties =new Properties()

keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

android{

buildTypes{

    release{

        signingConfig signingConfigs.release

    }

}

修改成

signingConfigs{

    release{

        keyAlias keystoreProperties['keyAlias']

        keyPassword keystoreProperties['keyPassword']

        storeFile file(keystoreProperties['storeFile'])

        storePassword keystoreProperties['storePassword']

    }

}

buildTypes{

    release{

        signingConfig signingConfigs.release

    }

}

之后在执行 flutter build apk打包就签名了。

在有签名文件的情况下获取应用签名：

keytool -list -v -keystore 签名文件路径

MD5就是文件签名：复制出来去掉:就可以使用了。

Q4: 【Android开发学Flutter】Xcode编译问题汇总

Xcode编译经常遇到各种问题，处理起来费时费力，挺打击学习积极性的。记录下这些问题，方便自己也帮助后来人。

编译的时候遇到：

网上有很多解决方法，我是用这个方法解决的：

编译的时候遇到：

解决办法：

Project - User-Defined - FLUTTER_ROOT 改成本地 flutter SDK路径

感谢 issues 上的小哥，给你个?

在项目目录下执行 flutter run 可以正常运行到手机，但是在Xcode build 还是有问题。

这时需要手动添加 FLUTTER_ROOT 到 User-Defined ：

添加之后：

就可以正常在Xcode build 安装到手机了。

flutter build ios 后出现：

pod install 后出现：

解决办法：

这是因为terminal没有走代理的流量，

使用 git config --global http.proxy "localhost:port" ，设置代理。

port是端口号，根据不同的vpn不一样，我的端口是10080。

执行 git config --global http.proxy "localhost:10080"

Xcode build 的时候出现：

解决办法：打开 ios/Podflie 文件：

关于 bitcode 的问题，我检查了下用到的第三方SDK，应该是百度地图的问题，我引入了个第三方插件（吐槽下没官方插件），百度地图有支持和不支持 bitcode 的两个SDK，我取消这个插件就没有报这个错了，奇怪的是，再次引入同一个插件，也可以正常打包，所以说这个问题还没有完全解决。

大家可以试下这个处理方法：

TARGETS - Build Seettings 搜 arm ，试一下把其他删除，只留下armv7跟armv7s或者只留下armv7

解决办法：

我是clean Xcode之后就可以了

解决办法：

用的是P12证书，改成手动签名：
