When you or your team develop a huge project using Flutter or Dart, it sometimes happens that many Dart files have unused import and output warning messages by Dart Analysis.
If you feel it is annoying, use the unused_import_remover package, which helps you with such an annoying problem.
You can choose the directory in which you want to remove the unimportant package. you execute the below command.
dart pub run unused_import_remover
That's all!
After you have executed the command, unused_import_remover checks all dart files under the directory you selected recursively, finds unused import package -> remove!!
You can get the benefits. An example is written below.
Before
import 'dart:async';
import 'dart:cli';
import 'dart:collection';
class Test1{}
After
class Test1{}
add unused_import_remover package in your project
dart pub add dev:unused_import_remover
dart pub run unused_import_remover *DIRECTORY_PATH*Ensure that you have to set DRECTORY_PATH, not FILE_PATH
Correct
dart pub run unused_import_remover ./
dart pub run unused_import_remover ./*DIRECTORY_NAME*/
You don't have to pub last /.
dart pub run unused_import_remover ./*DIRECTORY_NAME*
Incorrect
dart pub run unused_import_remover ./*.dart
dart pub run unused_import_remover ./*.dart
dart pub run unused_import_remover ./specific_file.dart
