[AVLE] Editing account's profile using Keychain

I have implemented editing account's profile using keychain.

I thought there is no function to update profile in steem keychain. But it was my misunderstanding.

I can use the requestBroadcast function to update profile like this for Flutter.

 final operations = dartJs.JsObject.jsify([
        [
          'account_update2',
          {
            'account': username,
            'json_metadata': '',
            'posting_json_metadata': jsonEncode(profileMeta)
          },
        ]
      ]);

      await steemKeychain.requestBroadcast(
        username: username,
        operations: operations,
        keyType: 'Posting',
        callback: dartJs.allowInterop(
          (response) {
            print('requestBroadcast. updateProfile: ${response['message']}');
            print(
                'requestBroadcast update profile  response success: ${response['success']}');
            if (response['success']) {
              // handleKeychainResult(response);
            } else {
              printError('failed to update profile. ${response['message']}');
            }
          },
        ),
      );

Edit Account's Profile

To edit the profile, click the gear button in the profile screen.

Update Profile

Here I changed the display name to "etain12"

After clicking the update button, then keychain appears like above.

This operation seems not applied directly when I check in steemit.com.

But when visiting steemworld.org, I can see the account_update2 operation right there!

Based on my development experience, it takes some time to be updated. Let's see what will happen after some time.
