signingConfig signingConfigs.release

Important is signingConfig signingConfigs.debug -> signingConfig signingConfigs.release

    signingConfigs {
       release {
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
           storePassword keystoreProperties['storePassword']
       }
    }
    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.release

            minifyEnabled true
            useProguard true
        }
    }
}

EDITED : 27-Dec-18

for package name just change in build build.gradle only

defaultConfig {
    applicationId "your.package.name"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

flutter create --org com.yourdomain appname

拆分widget

永遠不要使用方法返回的形式創建可重用的widget，始終將它們封裝到StatelessWidget中。 注意這個結論中的可重用。
