flutter buildapp bundle failed

I am trying to releas my app on play store and the command flutter build appbundle failed:

thi was the error:

Target aot_android_asset_bundle failed: IconTreeShakerException: ConstFinder failure: ../../Documents/FlutterDevelopment/SDKS/flutter/bin/cache/artifacts/engine/darwin-x64/const_finder.dart.snapshot: Error: Error when reading '../../Documents/FlutterDevelopment/SDKS/flutter/bin/cache/artifacts/engine/darwin-x64/const_finder.dart.snapshot': No such file or directory


To disable icon tree shaking, pass --no-tree-shake-icons to the requested flutter build command

this is the key.properties:

keyAlias=upload storeFile=../app/upload-keystore.jks

And I have my upload-keystone.jks file in android/app

Here is the build.gradle:

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
