vscode configures the flutter development environment without installing a third-party Android emulator

1. Get Flutter SDK

1. Click the installation package below to get the latest version of Flutter SDK for the stable release channel: Flutter SDK

2. Unzip the compressed package, and then place the flutterentire directory in the path where you want to place the Flutter SDK** (be careful not to have a Chinese directory)**

3. Configure the environment variables of the Windows system. In the User Variables column, add flutter\binthe full path to the directory in Path. For example:
   

4. After configuring the environment variables, you can open the cmd window of your computer and use the command

flutter doctor

The above command will check your existing environment and present the detection results in the form of a report. Read what it displays carefully and check to see if there is any software that has not yet been installed or if there are additional steps that need to be completed (usually in bold ).
The following problems usually occur during the first installation:

[-] Android toolchain - develop for Android devices
    • Android SDK at D:\Android\sdk
    ✗ Android SDK is missing command line tools; download from https://goo.gl/XxQghQ
    • Try re-installing or updating your Android SDK,
      visit https://flutter.cn/docs/setup/#android-setup for detailed instructions.

This is because we have not configured the corresponding Android development environment. Next, configure the Android environment.
