How To Flutter Fetch Device Info On Android And Ios App

Posted By Bajarangi soft , Posted On 27-11-2020

device info is fetched from the both Android & iOS devices and these information can be used to track the usage of the app and which later on can be helpful to provide better services. Some times few apps provide some offers to the users than may be for new users or once per user depending upon the terms so here we need to limit the usage of the offers multiple times so using this device info you can validate the devices and avoid multiple usages.

How To Flutter Fetch Device Info On Android And Ios App

Fetch Device Info On Android
Step 1
cannot directly remove the time stamp from Fetch Device Info On Android but using the intl.dart package we can easily filter the date stamp from time stamp. So open your flutter project’s pubspec.yaml in code .

dependencies:
  flutter:
    sdk: flutter
  device_info: ^1.0.0

Step 2
After done saving the pubspec.yaml file, Open your flutter project root folder in Command Prompt or Terminal and execute flutter pub get command.

flutter pub get
