Flutter Learning-01-Environmental Construction on Mac

Little knowledge, big challenge! This article is participating in the creation of " Tips for Programmers ".
I had a simple study before, and today I started to learn flutter, and recorded the knowledge points learned by flutter, and recorded my own knowledge points to learn.

1. Flutter installation

There are many online tutorials about flutter installation. Here, record your own installation of flutter environment, flutter's official website

After clicking, select install and we choose the macOS environment

Here we choose the stable version to download

1.1 Unzip and install the Flutter SDK

1.2 Configure the image file

We need to configure the image file after decompression, you can refer to the official website instructions

If you are installing or using Flutter in China, it may be helpful to use a trusted local mirror site that hosts Flutter dependencies. flutterTo instruct the Flutter tools to use an alternate storage location, you need to set two environment variables PUB_HOSTED_URLand before running the command FLUTTER_STORAGE_BASE_URL.

 export PUB_HOSTED_URL=https://pub.flutter-io.cn
 export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

The old version Macof the computer terminal is used bash, and its configuration file path is ~/.bash_profile;

The default after the new system is zshthat we will have two configuration files, so we only need to zshrcadd the following instructions at the end of the file to directly import bash_profileall the environment variables in the filezshrc

if [ -f ~/.bash_profile ]; then 
    . ~/.bash_profile;
fi

复制代码

we configure

export PUB_HOSTED_URL=https://pub.flutter-io.cn #国内用户需要设置
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn #国内用户需要设置
export PATH=/Users/*****/****/flutter/bin:$PATH
复制代码

After the configuration is complete, reopen the terminal, or enter the command directly in the terminal to reload the configuration:

# zsh 指令
source ~/.zshrc
