As flutter2.0 release, believe that many students are excited heart, trembling hands, want to try a wave quickly, do a person to eat crabs, himself with such a mood, head of a local thermal flutter version update to 2.0, eaten crab, but returned to the project code, a open, a piece of red, all kinds of error, I drop darling ~, and quickly back to the version of the previous stable version!

I would like to introduce a version management tool, FVM, for Flutter. I recommend Homebrew to install FVM.

  1. If your computer doesn’t have oneHomebrewIf so, go fuck itwebsiteViewing the installation method is a simple two-step process
  • Install the brew:git clone git://mirrors.ustc.edu.cn/homebrew-core.git//usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1(If that fails, try substituting:/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"This command)
  • Install the brew cask:git clone git://mirrors.ustc.edu.cn/homebrew-cask.git//usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask --depth=1If the installation fails, you can use the following command to install:
    • git clone https://mirrors.ustc.edu.cn/homebrew-cask.git/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask
    • git clone https://gitee.com/excelsi0r/homebrew-cask-versions.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask-versions
  1. Install FVM via BREW:
// Brew tap xinfeng-tech/ FVM // brew install FVMCopy the code

3. After the installation is successful, you need to configure your environment variables in the script tool: Because the MAC script tool has two. Bash and

  • If it is.bashAs the default Shell, it can be used in terminalsopen -e .bash_profileCommand open file
  • If it is.zshAs the default Shell, it can be used in terminalsopen .zshrcCommand open file

Add the following command to your Shell file to configure it

    export PUB_HOSTED_URL=http://mirrors.cnnic.cn/dart-pub
    export FLUTTER_STORAGE_BASE_URL=http://mirrors.cnnic.cn/flutter 
    export FVM_DIR="$HOME/.fvm"
    source "/usr/local/opt/fvm/init.sh"
Copy the code

Basic use of FVM

  1. View the FVM version
    fvm --version 
Copy the code

2. Using FVM, install a version of Flutter, such as Flutter 2.0

FVM install 2.0.0Copy the code

3. Check the current version of Flutter installed on FVM. Since I have 1.22.4 and 2.0.1 installed locally, I have two versions of Flutter installed locally

~ apple$FVM list current => 1.22.4-stable installed versions: 1.22.4-stable => 1.22.4 2.0.1-beta => 2.0.1 Default => 1.22.4 Latest => 1.22.4Copy the code

4. Set up different VERSIONS of Flutter for different projects

  • At the terminal, the CD goes into the project
  • useFVM use 1.22.4 - localSet the project’s FLUTTER version to 1.22.4

At this point, you have completed the installation and basic use of FVM

Configuration for using Android Studio for project development

In the use ofAndroid StudioWhen we were talking aboutflutter 和 dartShould be local to the configurationflutterVersion, so here you also need to configure to followfvmVersion change
  1. Configure the Flutter version of Android Studio
  • Open the Android Studio tools, find your preferences, and search for them in the search boxflutter 在 Languages & FrameworksUnder the SDK, there is a Flutter SDK path. On the far right, there is a button to select the path of the Flutter SDK. When you click on it, the file directory will pop up/Users/apple/File path, and then select.fvm -> currentFile, clickOpenSave. If the/Users/apple/Under the file, no.fvmIf so, try itCommand + Shift + .The way to show hidden files to find.fvmfile

  1. Configure the Dart version of Android Studio
  • In the same wayLanguages & FrameworksSelect Dart, locate the Dart SDK path under SDK, and configure your path to/Users/apple/.fvm/current/bin/cache/dart-sdk

Now that the Android Studio developer tools have been configured, you can switch between local versions of Flutter and use the developer tools to develop Flutter

Supplementary ！！！！

It is best to configure the flutter path in the Shell script as.fvm/current, for example, my local configuration!!

Don’t be impatient, good good study, day day up!!
