Can't run flutter project, when I try to run shows this issue ,This is the error seen in console, I am new to flutter Please Help.

The plugin `advance_pdf_viewer` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

CodePudding user response：

you can use build flavours for run this project , there is some packages null safety , use no sound safety commands in terminal an run the project.

flutter build apk --flavor dev -t lib/main_dev.dart

use this command to run this project
