Customizable Rating Bar
Step 1: We cannot directly remove the time stamp from Customizable Rating Bar 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
flutter_rating_bar: ^3.0.1+1
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
