Very good question. Sometimes you may have a grey screen in the FF builder and when this happens or for some reason you cant open the project or a page you can try to open it using Safe Mode. It is not that you are going to use it everyday, but it is good to know that it exists and to have it in your arsenal or tools
Hi Dimitar you made a lot of amazing videos help a lot , thank you very much. Just have a qustoin ---is that possible can make custom code for send email with a attachment in flutterflow ?? tks
can you help me with the DataTable widget? I can pay you. I am trying to update the selected checkboxes using an AppState. its the only problem i can't solved. my is basically finished, however the the entire project is useless without this function.
please dont use data table and it will work. also when u have children always put the different child in a component or else your checkboxes will not work.
@@flutterflowexpert I need to build this website man. can I speak with you? where do i send the money? I've gotten rid of DataTables, now i'm back to using ListView, with children from a collection. Each child has a check box that selects a document and sends the document in to a DocReference list AppState. Howevere with the LIstView Children I am unable to create a 'select all' feature. So now all i can do is press a checkbox one by one and select a document to be placed into an AppState and then downloaded to a CSV file. selecting one document at a time is unusable for my user who needs data from 100+ documents. No user will click 100, 200, 1000 checkboxes. I would like a have a select all feature in addition to a user selection feature where the user may simply type a number and that number of documents are selected and sent to the DocReference list AppState so that they can download their CSV.
@@flutterflowexpert This one thing is holding up my entire website. I cant believe that I cant figure out what seems so simple. I've build like 20 pages, I have 12 cloud functions, and I cant figure out how to check all on a ListView. I'm losing my mind
Here is a way you can do that import 'package:encrypt/encrypt.dart' as encrypt; class EncryptionUtil { static final key = encrypt.Key.fromUtf8('16_byte_secret_key'); // Ensure your key length matches the algorithm's requirements static final iv = encrypt.IV.fromLength(16); // Initialization vector static final encrypter = encrypt.Encrypter(encrypt.AES(key)); static String encrypt(String data) { final encryptedData = encrypter.encrypt(data, iv: iv); return encryptedData.base64; } static String decrypt(String data) { final decryptedData = encrypter.decrypt(encrypt.Encrypted.fromBase64(data), iv: iv); return decryptedData; } }
Very cool. Do you happen to know where the dev environment initial screen is defined? I changed my initial page and the development environment starts on the login page. Can't find how to change it..
@@blackbeauty6781 You can security store the key using Firebase Cloud Function instead of API call. I made a lot of video about FB CF for example - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zVc4UuIT6Gk.html
