Android 14 Bluetooth Scanning Issue in latest version (1.0.5)

[nadeesh19]

Please i'm expecting quick solution for this.

I used thermal_printer: ^1.0.5 version. and my flutter version is Flutter 3.22.1 and this is my android build.gradle file

buildscript {
    ext.kotlin_version = '1.9.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.15'
//        id("com.google.gms.google-services") version "4.3.15" apply false
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

This is the Error log in my console.
