Why does the Flutter build failed with the error Could not resolve all files for configuration ':app:debugRuntimeClasspath'

I wanted to use the flutter video_payer api for displaying a video from the network in my app. I upgraded to the latest version and now, my app won't build. The following error is being displayed-

PBI: {"kind":"error","text":"Invoke-customs are only supported starting with Android O (--min-api 26)","sources":[{}],"tool":"D8"}

I can't figure out the issue. What seems to be the problem?

In the log, it says

The dependency contains Java 8 bytecode. Please enable desugaring by adding the following to build.gradle android { compileOptions { sourceCompatibility 1.8 targetCompatibility 1.8 } }

If you are using Java 8, add below code to your android/app/build.gradle

android {
  ...
  // Configure only for each module that uses Java 8
  // language features (either in its source code or
  // through dependencies).
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

If it doesn't work, try with Java 10 (in your case)

android {
      ...
      // Configure only for each module that uses Java 8
      // language features (either in its source code or
      // through dependencies).
      compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_10
        targetCompatibility JavaVersion.VERSION_1_10
      }
    }
