I'm currently trying to build a signed release APK on Windows using Flutter. I've performed the tasks outlined in the documentation on the flutter site. When I run the build command here's the output I get. It seems to be around the firebase plugins. Any ideas?
dependencies:
flutter:
sdk: flutter
firebase_auth: 0.4.0
firebase_database: ^0.3.0

Turns out, the best way to handle this is to make the following change in android/app/build.gradle:
android {
compileSdkVersion 26
buildToolsVersion '26.0.3'
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
applicationId "com.example.app"
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
// This is the main section that I've updated
// to get the release APK to build
buildTypes {
release {
profile {
matchingFallbacks = ['debug', 'release']
}
signingConfig signingConfigs.release
}
}
}
flutter {
source '../..'
}
dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
apply plugin: 'com.google.gms.google-services'
With this change I was able to build the release APK.
