Keep trying add to whatsapp

[elihaidv]

Hi. Thanks about this library. It helps a lot.
Version 0.0.4 is much better. But still one bug:

Steps:

1. Add package to WA
2. Exit form WA. Doesn't matter if package added or not.
3. Back to my app
4. My app trying to add the package again and again
5. Sometimes after that, WA crashing, or error message: "operation couldn't be completed(com.third-party-sticker 1000)"

My code:

  var stickerPack = WhatsappStickers(
        identifier: category.identifier,
        name: category.title,
        publisher: pack.publisher,
        trayImageFileName: WhatsappStickerImage.fromFile(
            '${category.directoryPath}/${category.trayImageFile}'),
        publisherWebsite: pack.publisherWebsite,
        privacyPolicyWebsite: pack.privacyPolicyWebsite,
        licenseAgreementWebsite: pack.licenseAgreementWebsite,
      );

      category.stickers.forEach((sticker) {
        stickerPack.addSticker(
            WhatsappStickerImage.fromFile(
                '${category.directoryPath}/${sticker.imageFile}'),
            sticker.emojis);
      });

      stickerPack
          .sendToWhatsApp()
          .then((value) => analytics.logEvent(name: 'SuccessfullyAddedPackage'))
          .catchError((err) {
        print(err);
        analytics.logEvent(name: 'FailedAddedPackage');
      });
