Flutter - Cross Platform & Allows CP Bluetooth Connection

Question

Hello everyone, I have some questions:
1) When developing an app using flutter, can it run the same both on IOS and Android? meaning you can write code in one language and have it running on multiple OS's...?
2) As far as I researched - you can't connect an Android phone with an IOS phone via Bluetooth. But, can you do it via 'flutter_blue' or anything else, is it somehow possible to make such a connection and transfer data over the bluetooth connection?
* And just to make sure, Flutter is the development kit, and dart is the language the code is being writen with. Am I correct?
Thanks.

1- yes you will write one code for both Android and ios, and you must be sure that the packages you use are support both android and ios.
