Flutter Blue Read characteristic UUID

问题

I am using flutter blue to connect with an adafruit feather board and read in/write some values. How would I go about setting up a new characteristic that I wished to read from? I have followed the example but am having difficulty reading the double values produced on my arduino code.

 //Read Uuid

 BluetoothCharacteristic readCharacter = new
 BluetoothCharacteristic(uuid: null, serviceUuid: 6e400001-b5a3-f393-e0a9- 
 e50e24dcca9e, descriptors: null,
  properties: null);
//Write UUID

I am unsure what the declaration of the specific Bluetooth Characteristic I desire requires as parameters. Documentation indicates a uuid which I am unsure how to format?

Additionally, if there are any other examples of a simple project reading and writing values with a user interface established it would be nice to view.
