Answer 1

I finally reproduced such kind of issue and could solve it by upgrading or downgrading the plugin or remove the plugin from.pub_chace and install it, in your case flutter_local_notifications .

Answer 2

open android\build.gradle find this

subprojects { project.evaluationDependsOn(':app')

project.configurations.all {
    resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'androidx.core' &&
                !details.requested.name.contains('androidx')) {
            details.useVersion "1.0.1"
        }
    }
}

delete project.configurations.all and all its content

the new code now looks like this

subprojects { project.evaluationDependsOn(':app') }

flutter clean flutter pub get
