Error I get while I'm trying to make android requirements.

Hello,
iam trying to match android requirements but i get that error:
FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:checkDebugAarMetadata'.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
2 issues were found when checking AAR metadata:

   1.  Dependency 'androidx.emoji2:emoji2-views-helper:1.4.0' requires libraries and applications that
       depend on it to compile against version 34 or later of the
       Android APIs.

       :app is currently compiled against android-33.

       Also, the maximum recommended compile SDK version for Android Gradle
       plugin 7.3.0 is 33.

       Recommended action: Update this project's version of the Android Gradle
       plugin to one that supports 34, then update this project to use
       compileSdkVerion of at least 34.

       Note that updating a library or application's compileSdkVersion (which
       allows newer APIs to be used) can be done separately from updating
       targetSdkVersion (which opts the app in to new runtime behavior) and
       minSdkVersion (which determines which devices the app can be installed
       on).

things that i changed to match requirement:
1- classpath 'com.android.tools.build:gradle:8.1.3'
2-ext.kotlin_version = '1.8.10'
3- minSdkVersion 21
4-`package com.example.payment_proj

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity

class MainActivity: FlutterFragmentActivity() {
}`

5- <style name="NormalTheme" parent="Theme.MaterialComponents"> in styles.xml in values and the other one in night-values folder

6-distributionUrl=https\://services.gradle.org/distributions/gradle-8.0-bin.zip
otherwise these things every other thing is default

I tried the recommanded instruction in the error that to update the android gradle plugin but i dont understand i have it like i showed above in step 6 its version is 8 not 7.3 (before i change it it was 7.3 but i did change it to match the requirements)
am i missing something ?
