CodePudding user response：

The error message tells you that there is a library which requires a higher SDK version (at least 23) than is currently configured as the minimum (19). The compiler recognizes this as an error, because your app would then probably not work on older devices.

If you would like to continue using this library, you will have to increase the minSDKVersion to at least 23. This can be done by editing the android/app/build.gradle file.

Inside this file, find the line stating minSDKVersion 19 and replace it with minSDKVersion 23.

This is also described in this question

CodePudding user response：

This error generally occurs when a package you use has a higher Minimum SDK version (the lowest version your app can support) and when you declare your app's minimum SDK version below than that declared in the package.

You can solve this using two methods:

Method 1

• Navigate to yourProjectRoot\android\app\build.gradle and then change minSdkVersion 19 to minSdkVersion 23.
• You can find the minSdkVersion in

def localProperties = new Properties()
//Other configs here........
android {

    //Other properties configured

    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 23 //**Make the change Here**
        //Other SDK properties....
    }
}
//Other code...........

Method 2

• Not really a solution but you can try finding another package at pub.dev which meets your need and has a minSDK version to 19
