I'm trying to run my app on android emulator and i keep getting this error :

   `The build failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetifier to solve the incompatibility.
    [!] Flutter tried to create the file `android/settings_aar.gradle`, but failed.
To manually update `settings.gradle`, follow these steps:
1. Copy `settings.gradle` as `settings_aar.gradle`
2. Remove the following code from `settings_aar.gradle`:
    def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
    def properties = new Properties()
    assert localPropertiesFile.exists()
    localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }
    def flutterSdkPath = properties.getProperty("flutter.sdk")
    assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
    apply from: "$flutterSdkPath/packages/flutter_tools/gradle  /app_plugin_loader.gradle"
Exception: Please create the file and run this command again.'

settings.gradle file :

include ':app'

 def localPropertiesFile = new File(rootProject.projectDir,   "local.properties")
    def properties = new Properties()

   assert localPropertiesFile.exists()
   localPropertiesFile.withReader("UTF-8") { reader ->     properties.load(reader) }

  def flutterSdkPath = properties.getProperty("flutter.sdk")
  assert flutterSdkPath != null, "flutter.sdk not set in    local.properties"
  apply from: "$flutterSdkPath/packages/flutter_tools/gradle   /app_plugin_loader.gradle"

Did you set up your project properly for AndroidX ? Instruction here

if even after that you are still facing this issue, you have to change gradle version

android/build.gradle---
classpath 'com.android.tools.build:gradle:3.5.4'

after making any change in your project you need to refresh project cached settings run in terminal

 flutter clean 
flutter pub get

Something is wrong related to your android/settings.gradle file. It should look like this:

include ':app'

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

And your android/app/build.gradle file should look like this:

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))
}

    }
    buildTypes {
