I googled and i find that compileSdkVersion must be 28. This is my build gradle app:

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "net.mobile"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

But i still got error?

How you build apk? What IDE are you using? Did your project able to run? — John Joe, Apr 27 '20 at 16:56

The error is not completed. From the exception, it probably fail on plugin `webview_flutter`. What version you using? — John Joe, Apr 27 '20 at 17:19
This is my all dependencies https://paste.ubuntu.com/p/kTs8RzDFXS/ @JohnJoe — Cyrus the Great, Apr 27 '20 at 17:24
post the error after `The plugin webview_flutter could not be built due to the issue above. Running Gradle task 'assembleAarRelease'...` — John Joe, Apr 27 '20 at 17:26
Those error was completed . https://paste.ubuntu.com/p/S3FjR6jxvb/ @JohnJoe — Cyrus the Great, Apr 27 '20 at 17:28
`The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.` You need to refactor it to `Androidx`. — John Joe, Apr 27 '20 at 17:40

You haven't accepted some android licenses. Please read flutter doctor output properly and run flutter doctor --android-licenses

EDIT:

Also it seems you dont have libraries for linux.

On Debian/Ubuntu/Mint: sudo apt-get install lib32stdc++6

On Fedora: dnf install libstdc++.i686

On Arch: pacman -S lib32-gcc-libs
