Errore while building apk with Flutter

I have already tried using the –null-safety mode but than my app doesn’t work.
When I use the debug mode on the emuletor I have no problems.
Any idea?

Here the error message.

flutter build apk 

 Building with sound null safety 

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:plugin_platform_interface

For solutions, see https://dart.dev/go/unsound-null-safety

    Seems some dependencies not supporting null-safety and to solve this you can upgrade your dependencies

    To upgrade packages upto date

    Run
    flutter pub outdated --mode=null-safety to print all outdated packages.,

    And flutter pub upgrade --null-safety to upgrade all packages automatically

    Or use below command to run your application without null-safety.

    flutter run --no-sound-null-safety

    Better to keep working git branch before update

    I also facing release apk issue. I tried to change in the gradle.properties.

    org.gradle.jvmargs=-Xmx1536M
android.useAndroidX=true
android.enableJetifier=false <---- make it false.

    Then run flutter build apk command
