Same here. It stopped working since latest Flutter upgrade. Works in debug mode but not in release.

Post both your gradle files.

nobody is specifying what version of the plug-in they’re using.

[Z6P0]

build.gradle:

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "${project(':background_fetch').projectDir}/libs" }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

Using latest plugin version and latest Flutter version.

First-of-all, the maven repo jcenter() has been deprecated since 2021.

second, you’ve not fully implemented the Android setup instructions linked in the readme (the ext vars).

I suggest you generate a fresh hello-world app and compare the changes in the default build.gradle with those in your own app.

you’ve failed to properly upgrade your app with the latest requirement of the latest flutter SDK. That’s why you have problems.

I am getting same issue
[BUG] AAPT: error: resource android:attr/lStar not found.
This my bulid.gradle file

allprojects {
repositories {
google()
mavenCentral()
maven { url "${project(':background_fetch').projectDir}/libs" }
}
}

rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
delete rootProject.buildDir
}

See my comment above: #369 (comment)

you did not fully implement the Setup Instructions (ext vars). Go back and review the Setup Instructions. Yes, they are important.
