Same Problem here,
any solution?

As per version 1.2.0:

Library now requires Java 17 or higher and your app must build on API 34 (14 Upside Down Cake) on Android.

Thanks for your response. Issue still there with:

`compileSdkVersion 34
ndkVersion flutter.ndkVersion

compileOptions {
    sourceCompatibility JavaVersion.VERSION_17
    targetCompatibility JavaVersion.VERSION_17
}

kotlinOptions {
    jvmTarget = '1.8'
}`

Run flutter pub upgrade. Also, run flutter clean so that it rebuilds from scratch.

ok, thanks.
i think the problem was an overridden transitive dependency of package_info_plus (overriden to 4.2.0). But that justs switched the problem to package_info_plus:

Execution failed for task ':package_info_plus:compileReleaseJavaWithJavac'.
error: invalid source release: 17

To be precise i changed the jvmTarget to 17 too. As mentioned here #2723 i made the same changes.

plz tell how to solve this error

[Merlinski]

For me the problem is solved exacly as dexcibed here..

If u depend on package_info_plus too and have issue with it have a look at
package_info_plus changelog

there are some requirements to fullfill since version 6.0.0
in my case i hade to migrate to grade 8.4 for android part
