Flutter Support
Dart Pad also supports the Flutter framework, allowing developers to create interactive user interfaces and mobile apps. It provides documentation and examples for both Dart and Flutter, making it a valuable resource for learning and experimentation.
Getting Started with Flutter in Dart Pad
To begin using Flutter in Dartpad, follow these simple steps:
- Open Dart Pad: Visit Dartpad in your web browser.
- Starting a New Project: Click on the “New Pad” option to initiate a new project.
- Select Flutter: Choose the “Flutter” option to start working with the Flutter framework.
Writing and Executing Code
In the newly created project, you’ll find a sample code for generating a “Hello, World!” message. The code is displayed in the left section, and you can execute it by clicking the “Run” button. Alternatively, you can use keyboard shortcuts ([Cmd] + [Enter] or [Ctrl] + [Enter]) for running the code.
Exploring Samples and Editing Code
Dart Pad provides additional sample Flutter codes accessible through the “Samples” button. You can edit or write your own code directly within the interface. Utilize the “Reset” button to discard changes or the “Format” button to organize your code.
Enhancing the Development Experience
While editing code, you can take advantage of various keyboard shortcuts for tasks like commenting out ([Ctrl] + [/] or [Cmd] + [/]), selecting all ([Ctrl] + [A] or [Cmd] + [A]), and quickly fixing code issues ([Alt] + [Enter]).

Viewing on Different Screen Sizes
Adjust the divider between the code editor and display to visualize your project on various screen sizes. Minimize the code section for a tablet-sized view or maximize it for a mobile-sized display.
Exploring Flutter Widgets
To utilize Flutter widgets implementing material design, include the following line in your code: import 'package:flutter/material.dart'. You can access documentation for any widget or named argument by clicking on the document option below.
Saving and Sharing Code
While Dartpad doesn’t support saving code directly, you can utilize GitHub gists for this purpose. Simply open your GitHub account, create a new gist with a description and file name, and paste the code from Dart Pad. Then, obtain the gist ID and combine it with https://dartpad.dev/ to share your code along with its output.
Limitations
Keep in mind that Dartpad does not support the use of third-party libraries, and it is not intended for writing and deploying fully-fledged Flutter applications. Instead, it serves as a platform for exploring and experimenting with the Flutter framework.
