How to get timezone, Language and County Id in flutter by the location of device in flutter?

问题

I am new to flutter, and I want to get Timezone, language, and county Id when I run my project on my device android or iOS. It should detect Timezone, language and country Id from the location of the device. I am newbie to flutter and don't know how can I get these. Is there any library or I can get these via the internal library, please suggest another way.
