Mac配置github公钥 publickey

flutter运行到ios上出现错误

原因是没有配置github公钥，解决办法

github账号 test@126.com为例
终端输入：

ssh-keygen -t rsa -b 4096 -C "test@126.com"

192:~ abc$ ssh-keygen -t rsa -b 4096 -C "test@126.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/abc/.ssh/id_rsa):

设置密码，可以直接回车跳过

Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/abc/.ssh/id_rsa.
Your public key has been saved in /Users/abc/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:nO/2ou/VPRpS/aufbjXyiAkWytrL3REp/nSJNaxRGJc test@126.com
The key's randomart image is:
+---[RSA 4096]----+
|           . ..  |
|            +E   |
|           . .   |

|      o ..o*++=.=|
|     .....*++.oo+|
|       oo*+=.o== |
+----[SHA256]-----+

查看公钥并复制

cat id_rsa.pub

192:.ssh abc$ cat id_rsa.pub
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

== test@126.com
