The standard template does not include this tag but allows Internet access during development to enable communication between Flutter tools and a running app. ### ### ### ### ### ### ### ### ### ### SOME USEFUL TIPS: Tip 1: YOU CAN GENERATE KEY-PAIR AND SELF-SIGNED CERTIFICATE FROM COMMAND LINE AS WELL. C:\Users\Ashish Jain\AndroidStudioProjects\survival>keytool -genkey -v -keystore e:/key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias key0 Enter keystore password: Re-enter new password: What is your first and last name? ... What is the name of your organizational unit? ... What is the name of your organization? ... What is the name of your City or Locality? ... What is the name of your State or Province? ... What is the two-letter country code for this unit? ... Generating 2,048 bit RSA key pair and self-signed certificate (SHA256withRSA) with a validity of 10,000 days ... Enter key password for [key0] (RETURN if same as keystore password): [Storing e:/key.jks] Warning: The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore e:/key.jks -destkeystore e:/key.jks -deststoretype pkcs12". ............................ Tip 2: FINDING THE LOCATION OF THE 'zipalign' PROGRAM ON WINDOWS C:\Users\Ashish Jain>dir /s *zipalign* Volume in drive C is Windows Volume Serial Number is 8139-90C0 Directory of C:\Users\Ashish Jain\AppData\Local\Android\Sdk\build-tools\28.0.3 09/14/2019 09:43 PM 744,960 zipalign.exe 1 File(s) 744,960 bytes Directory of C:\Users\Ashish Jain\AppData\Local\Android\Sdk\build-tools\29.0.2 09/08/2019 11:35 PM 731,648 zipalign.exe 1 File(s) 731,648 bytes Total Files Listed: 2 File(s) 1,476,608 bytes 0 Dir(s) 75,927,285,760 bytes free ............................ Tip 3: GENERATING .APK FILE FOR FLUTTER CODE FROM COMMAND LINE: C:\Users\Ashish Jain\AndroidStudioProjects\survival>flutter build apk You are building a fat APK that includes binaries for android-arm, android-arm64. If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size. To generate an app bundle, run: flutter build appbundle --target-platform android-arm,android-arm64 Learn more on: developer.android.com To split the APKs per ABI, run: flutter build apk --target-platform android-arm,android-arm64 --split-per-abi Learn more on: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split Initializing gradle... 4.0s Resolving dependencies... 15.5s Running Gradle task 'assembleRelease'...
