I have same problem

[JAICHANGPARK]

Solved Change compileSdkVersion & targetSdkVersion 27 to 28

compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "dev.bessems.usbserialexample"
        minSdkVersion 24
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

This worked for me. In the build gradle (not of your app but the one in the package) change the compileSdkVersion (from 27 to 28). So... my guess is that in the next update of this package, if they upgrade the gradle, it will solve this issue

[diegomxc]

Solved Change compileSdkVersion & targetSdkVersion 27 to 28

compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "dev.bessems.usbserialexample"
        minSdkVersion 24
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

Please consider this change in the next version.

I still have the same problem. I tried to create a new project, and copy the code from the old one. In a new project, there is already "compileSdkVersion 28" also "targetSdkVersion 28"

Changing to 29 doesn't help.

Any suggestions?

Wich gradle are u changing ? , U need to open gradle from usbserial, not app gradle.

[mrincognito39]

Yep diegomxc is correct, you will need to open the external Libraries/Flutter Plugins/usb_serial-0.2.3/android/build.gradle file and change the compile sdk version from 27 to 28.

[Matt1700]

I've created a pull request that should solve this problem (it literally just changes the target SDK version to 28). Meanwhile, as @mrincognito39 said you can just manually change your pub cache. You'll find the pub cache in the Flutter SDK path (you can run flutter pub get -v to see the full path).
