Support for Multiple Cameras at Once in Flutter
Akash Mishra discussed the need for developers to access and display multiple cameras simultaneously when using Flutter. He noted that although Flutter does not provide native support for this, third-party packages, such as the camera by flutter.dev or camerawesome by apparence.io package, can be used to wrap the native camera APIs of both Android and iOS in order to provide a high-level Flutter API for controlling the device's camera. However, there are still limitations to the number of cameras that can be accessed and displayed at once.

Can an app be decompiled and methods used to modify databases?
This isn't specific to flutter but using flutter as an example... Suppose I have an app that allows a user to change their username stored in firebase via a method called updateUsername. This calls firebase and updates that document with a new username.I know that people can decompile an apk (no idea about iOS version) and that would in theory expose the updateUsername method along with other classes and config files. What is stopping someone from calling that update method directly and passing in some random username and someone's user id and updating it maliciously? Couldn't they, with decompiled code, modify their local code and run the app and change data in the database?
Developing with pub.dev packages
Some of the projects I'm developing rely on a couple of pub.dev packages. All the packages I'm using have MIT licences. Can I publish my projects commercially (and potentially make money) using these packages?Also, is it bad practice to program using external packages?Any advice would be appreciated.
