If you've encountered the PlatformException(no_available_camera, No cameras available for taking pictures.) error while developing a Flutter application, you are not alone. This is a common issue faced by many developers, especially after merging projects or making changes to configurations related to camera access. In this post, we’ll discuss why this error occurs and provide a straightforward solution to fix it.

Understanding the Problem

The error typically arises when your application tries to access the device’s camera for taking pictures but fails to find any available camera resources. This can occur due to various reasons, including:
