The first step is to configure environment variables
Configure environment variables in user variables
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
The second step is to download the SDK of Flutter
Download the version of SDK you want from the fluterSDK address . It is recommended to download the latest stable version for beginners.
The third step is to decompress and configure environment variables
Unzip the downloaded ZIP package into the folder where you want to store fluter. It is recommended that the folder not have English to prevent errors when compiling and searching.
Configure PATH in the user variable. If it already exists, add it later; if it is separated, create a new PATH variable. The configured value is the address of the bin folder in your decompressed flutter file
For example, if I unzip it on the D drive, then my corresponding path is D:\fluter\flutter\bin
After saving, remember to restart the computer or there will be problems running fluter doctor
Run fluter doctor to know whether the configuration is missing or successful
The corresponding X in the command is something we have not configured successfully. Here, the Android editor Android Studio editor configuration link is missing and installed to the place you want to install according to your own installation path.
Go to the plug-in market to download the plug-in
Sometimes when you run flutter doctor, this happens because the local user environment variables are not configured. Configure an ANDROID_HOME
