    2. Icon Generation https://icon.kitchen/
    3. flutter pub add flutter_launcher_icons
    4. flutter pub get
    5. flutter pub run flutter_launcher_icons
 2. Alterando o nome do app   
    6. flutter pub global activate rename
    7. flutter pub global run rename --appname "Nome do Meu App"
    8. flutter pub global run rename --bundleId com.nomedomeuapp
 3. Signing the app
    9. Na pasta Android, criar o arquivo key.properties
    10. 
        storePassword=<password from previous step>
        keyPassword=<password from previous step>
        keyAlias=upload
        storeFile=path/android/app/upload-keystore.jks     
    11.   keytool -genkey -v -keystore path\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload
    12. Mover o arquivo para a pasta android\app\upload-keystore.jks
    13. Alterar o caminho no key.properties para storeFile=..app/upload-keystore.jks 
 4. Configure signing in gradle
    14. Abrir arquivo \android\app\build.gradle
    15. colar antes da seção andorid
            def keystoreProperties = new Properties()
            def keystorePropertiesFile = rootProject.file('key.properties')
            if (keystorePropertiesFile.exists()) {
                keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
                }

   Find the buildTypes block And replace it with the following signing configuration info:

      signingConfigs {
       release {
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
           storePassword keystoreProperties['storePassword']
       }
   }
   buildTypes {
       release {
           signingConfig signingConfigs.release
       }
   }
5. Limpa e builda
    flutter clean
    flutter build appbundle    
6. Alterar o gitignore para
    key.properties
    **/*.keystore
    **/*.jks    
7. flutter build appbundle
