Yes, Flutter is free and open-source software. You can download and use Flutter without paying anything. Additionally, Flutter’s open-source nature allows developers to contribute to the codebase, suggest improvements, and report issues.
Flutter is licensed under the BSD (Berkeley Software Distribution) license, which is a permissive open-source license. This means that you are free to use, modify, and distribute Flutter, as long as you comply with the terms of the license. The BSD license allows for commercial use of Flutter, so you can use Flutter to develop commercial apps without any legal restrictions.
However, keep in mind that while Flutter is free to use, you may need to pay for third-party services or tools to develop, deploy, and distribute your Flutter apps. For example, you may need to pay for cloud hosting services, app store fees, or third-party plugins and packages.
Overall, Flutter’s free and open-source nature makes it an accessible tool for developers to build high-quality, cross-platform mobile apps.
