Building a development environment for Flutter on Win10 --- Flutter SDK Install (2020 preservation version)

I started Flutter.

I want to develop an app with the insanely popular framework Flutter, but I've heard that it's a hassle to build a development environment for Flutter. Therefore, the text is created as a memorandum.

There are three main parts. ● Download ● Setting environment variables ● Dependency confirmation

Now let's get down to the main topic.

download

First, select Windows from the Official Site and select Windows. Go to the Windows installation screen and click the link flutter_windows_1.22.3-stable.zip to start the download. Place the downloaded file anywhere you like, right-click and click Unzip Here to unzip it. The result of decompression looks like this. So you can delete the flutter_windows_1.22.3-stable.zip file.

Setting environment variables

Open the above flutter folder, enter the child folder of bin, copy the following path

C:\flutter-stabe\flutter\bin

Click the Windows icon at the bottom left, press the Settings icon, Select a system Click on version information Click System Information under Related Settings to move to Control Panel Home. Click Advanced System Settings to go to System Properties. Click Environment Variables in System Properties Select Path in the system environment variable and press the edit button to pop up the edit windows for the environment variable name. Press the new button, paste the path you just copied, and press the OK button.

Start the command prompt on Windows and check with the following command.

flutter --version

If you get the result as below, it was installed correctly.

Flutter 1.22.3 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 8874f21e79 (9 days ago) • 2020-10-29 14:14:35 -0700
Engine • revision a1440ca392
Tools • Dart 2.10.3

Dependency confirmation

It is necessary to install some related software and tools for building the development environment of Flutter. So let's check the dependency with the following command.

flutter -doctor

Right now, I only install the Flutter SDK, so it's okay if you get the following results.

Doctor summary (to see all details, run flutter doctor -v):

      On first launch it will assist you in installing the Android SDK components.
      (or visit https://flutter.dev/docs/get-started/install/windows#android-setup for detailed instructions).
      If the Android SDK has been installed to a custom location, set ANDROID_SDK_ROOT to that location.
      You may also want to add it to your PATH environment variable.
