flutter:设置当前的channel并更新版本(从master切换到stable)

一，查看当前flutter和dart的版本:

说明：我们当前的channel是master,所以可以看到flutter和dart版本均为pre或dev版本:

liuhongdi@liuhongdideMacBook-Pro ~ % flutter --version
Flutter 3.7.0-27.0.pre.25 • channel master • https://github.com/flutter/flutter.git
Framework • revision c9affdba9d (7 hours ago) • 2023-01-25 21:25:02 -0800
Engine • revision 8f1e5dc1b1
Tools • Dart 3.0.0 (build 3.0.0-157.0.dev) • DevTools 2.20.1

liuhongdi@liuhongdideMacBook-Pro ~ % dart --version
Dart SDK version: 3.0.0-157.0.dev (dev) (Mon Jan 23 20:06:50 2023 -0800) on “macos_x64"

二，查看flutter当前的channel

liuhongdi@liuhongdideMacBook-Pro ~ % flutter channel
Flutter channels:
* master
  main
  beta
  stable

可以看到当前的channel是master,我们把它切换为stable,

这样可以保障库的稳定性

三，设置当前channel,切换到stable

liuhongdi@liuhongdideMacBook-Pro ~ % flutter channel stable
Switching to flutter channel 'stable'...
git: Switched to a new branch 'stable'
git: Branch 'stable' set up to track remote branch 'stable' from 'origin'.
Successfully switched to flutter channel 'stable'.
To ensure that you're on the latest build from this channel, run 'flutter upgrade’

四，再次使用flutter channel命令时，会开始下载

1，查看当前的channel

liuhongdi@liuhongdideMacBook-Pro ~ % flutter channel      
Downloading Darwin x64 Dart SDK from Flutter engine b24591ed328a2d4ce6505819e2f5898a78132f7f…

Flutter channels:

  main

再次更新flutter

liuhongdi@liuhongdideMacBook-Pro ~ % flutter upgrade
Flutter is already up to date on channel stable
Flutter 3.7.0 • channel stable • https://github.com/flutter/flutter.git
Framework • revision b06b8b2710 (3 days ago) • 2023-01-23 16:55:55 -0800
Engine • revision b24591ed32
Tools • Dart 2.19.0 • DevTools 2.20.1

可以看到flutter并未进行下载操作，因为执行flutter channel时就已做了更新，

更新是为把版本切换到stable channel下的新版本

五，查看切换channel后的版本

liuhongdi@liuhongdideMacBook-Pro ~ % flutter --version
Flutter 3.7.0 • channel stable • https://github.com/flutter/flutter.git
Framework • revision b06b8b2710 (3 days ago) • 2023-01-23 16:55:55 -0800
Engine • revision b24591ed32
Tools • Dart 2.19.0 • DevTools 2.20.1
liuhongdi@liuhongdideMacBook-Pro ~ % dart --version
Dart SDK version: 2.19.0 (stable) (Mon Jan 23 11:29:09 2023 -0800) on "macos_x64"

可以看到在stable channel,不管是dart还是flutter都已切换至稳定的版本，不再是pre或dev版本
