the problem did not resolve with multidex , only way was to remove it and follow this link

resolve multidex issue

it worked by removing these in your gradle

multiDexEnabled true

and

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

and changing from this

buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

to this

buildTypes {
    release {
            signingConfig signingConfigs.release
            minifyEnabled true
            useProguard true
    }
    debug{
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

and in your path: /android/app

right click and create a file named proguard-rules.pro

and put these files inside the file

#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }

It seems some setups are still remaining for Firebase.
Checkout this link and set up the .json and .plist file accordingly in project.

If you further still facing the issue,
I would recommend some steps.
1) Delete all the build files of the project, invalid cache and restart android studio.
2) Follow the below changes in your project.

build.gradle file

android {
.....
defaultConfig {
......
 multiDexEnabled true//add this line
}
......
dependencies{
 compile 'com.android.support:multidex:1.0.1'//add this line
}

AndroidManifest.xml file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
....
<application
....
 android:name="android.support.multidex.MultiDexApplication" 
...>
 <activity   />
...

</application>

</manifest>
