Android 14 Bluetooth Scanning Issue in latest version (1.0.5) #22
Description
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.
