Flutter: How Can I Get Device_id And Device_token In Flutter 2.5.3?

I want to get device information such as device_id and device_token for google and facebook sign-in, so that i can get data for the next dashboard-page as in following code

Body:{
  "token": "string",
  "device_info": {
    "device_token": "lfkjklfl", <---- //this field i need 
    "device_id": "jgkfjdgkfjdlgfd"
  }
} 

i have used this device_info package for getting token, but their is no token type in this package

device_token only you can get via firebase messaging.
