Installing Flutter DevTool in Android Studio

Running a Flutter app used to be pretty hard; you can use these steps to make things easy for your app development.

Step 1: Install the Flutter plugin if you don’t have it yet. You can do this by opening Android Studio, going to settings->Plugins, and searching for Flutter in the Marketplace. Once you’ve installed the plugin, restart Android Studio to ensure everything is working.
Step 2: Make sure you have a device connected to the project and click the Run or Debug toolbar buttons.
Step 3: Now, you can launch DevTools from the toolbar/menu displayed in your Flutter project.

Installing DevTools from VS Code

Step 1: First, install the Dart extension, which is also needed to debug Flutter applications.
Step 2: Launch an app to debug your Flutter app. Initiate debugging in VS Code by clicking Run > Start Debugging (F5).
Step 3: Once debugging starts, the Dart Opens DevTools command becomes available in the VS Code command palette.

Install DevTools From the Command Line

Step 1: Using flutter on your computer, you can run:
flutter pub global activate devtools

Step 2: The above command helps you update or install DevTools. You can launch the DevTools with the help of the application server. Then, run the local webserver. Stick to the following command:
Serving DevTools at http://127.0.0.1:9100

Step 3: You will get the following output on the command line:
Serving DevTools at http://127.0.0.1:9100

After this, you can start an app to debug.

Summing Up

Certified and experienced Flutter app developers know how to bring the best out of DevTools to build flexible and scalable mobile apps.

DevTools gives you a full view of the layout tree and allows you to change many aspects of its visual presentation; Flutter developers can use DevTools along with the live widget inspector feature in the editor plugin to perform side-by-side layout comparisons. You can combine that with a bit of console magic to see how changes impact your app. This saves you a lot of time in debug mode when optimizing your apps for various screen sizes or layout permutations in Flutter.
