How to check the device OS version from Flutter?

问题:

Platform.operatingSystem will tell you whether you're running on Android or iOS.

How can I check which version of the device OS am I running on?

回答1:

There's a plugin for this exact purpose:

https://github.com/flutter/plugins/tree/master/packages/device_info

回答2:

You can use platform channels for this task. In native use os specific code to get version and resend it to flutter. Here is good example with battery level

回答3:

import 'dart:io' show Platform;

void main() {
  // Get the operating system as a string.
  String os = Platform.operatingSystem;
  // Or, use a predicate getter.
  if (Platform.isMacOS) {
    print('is a Mac');
  } else {
    print('is not a Mac');
  }
}

Dart SDK > dart:io > Platform

Here is the official article above, and if you want to check it is IOS or Andriod, you can use:

if (Platform.isIOS) {
  print('is a IOS');
} else if (Platform.isAndroid) {
  print('is a Andriod');
} else {
}
