Я внедрил flutterDownloader (это пакет для загрузки файлов в flutter) в свой проект, и когда я добавляю его в манифест Android, как указано в документе, и когда я делаю это, gradle показывает эту ошибку

** ошибка : **

в чем здесь проблема? Я пытался сделать именно то, что написано в документах, любая помощь?

вы должны привязать атрибут tools к вашему элементу манифеста:

 <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="[YOUR APP NAME]" xmlns:tools="http://schemas.android.com/tools" >
  

Я только что решил это! Вам нужно добавить эту строку в тег манифеста, на самом деле это первый тег в файле: xmlns:tools="http://schemas.android.com/tools"
