I keep getting the error message "Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'."
According to stackoverflow question transformClassesAndResourcesWithProguardForRelease FAILED I need to just add the following code to my proguard-rules.pro:
-ignorewarnings
-keep class * {
public private *;
}
Where do I find this proguard-rules.pro file? Do i need to create it myself and if so, whereabouts should I put in my app directory?
First, we will enable shrinking in the build file. Find build.gradle file which sits inside /android/app/ folder and add lines in bold
android {
...
buildTypes {
release {
signingConfig signingConfigs.debug
//add everything below
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
Next, we will create a configuration that will preserve the entire Flutter wrapper code. Create /android/app/proguard-rules.pro file and insert inside:
-ignorewarnings
-keep class * {
public private *;
}
DONE!
