I’ll be thank for any one help me to solve this problem

**This is the lib that I'll incloude it in pubspic**
  1. cupertino_icons: ^1.0.2
  2. cloud_firestore: ^2.5.4
  3. image_picker:^0.8.4+4
  4. firebase_storage: ^10.0.6
  5. random_string:^2.3.1

Solution

You have two solutions:

Option 1:

You need to target Android 21 as a minSdkVersion in /android/app/build.gradle file.

android {
    defaultConfig {
        // ...
        minSdkVersion 21   //*** LOOK AT THIS LINE ***
        targetSdkVersion 28
    }
}

Option 2:

You need to add multiDexEnabled true in /android/app/build.gradle file.

android {
    defaultConfig {
        // ...
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true   //*** LOOK AT THIS LINE ****
    }
}

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