[@shankaroffical3671]

one question, when i use firestore methods like update or read a document with my custom functions, it won't allow me to edit the function type like
Future myFunction(), what should i do , other than inbuild actions, because that's not flexible to use my comfortablity

[@Dimi-cv6qr]

Thank You for the great FlutterFlow University series!
One question: You do not check if the input in this case is nummeric or not? It is not necessary?

[@FlutterFlow]

Great question! We add a helper toString() in a lot of places to save you that step.

[@dr.anonymous4867]

Can anyone help me creating a fully functional custom widget in flutterflow

[@hmbv0202]

Why on Test Mode my page turn darker?

[@ta_helado]

cant we use a dependency?

[@FlutterFlow]

You can use the dependancies that are there but not other pub.dev packages. If you need those use Custom Actions.

[@HREproductions-lk9rn]

At the last part of the video 6:30 my variables menu doesn't have widgets.

[@cesarsfalcao]

Add the text field and its parameters will be available

[@victorbecerra4659]

[@victorbecerra4659]

Hi, my friend, could you please help me fix my Flutter custom action to get the video duration?
// Automatic FlutterFlow imports
import '/backend/backend.dart';

// DO NOT REMOVE OR MODIFY THE CODE ABOVE!
import 'dart:io';
import 'package:flutter_ffmpeg/flutter_ffmpeg.dart';
Future videoInformation(String video) async {
// get the media duration after uploading it from library or storage and return string in milliseconds
// Import necessary packages
// Create a function to get the media duration
Future videoInformation(String video) async {
// Create an instance of FlutterFFmpeg
final FlutterFFmpeg _flutterFFmpeg = FlutterFFmpeg();
// Get the media information using FFmpeg
final int rc = await _flutterFFmpeg.execute("-i $video");
// Check if FFmpeg was able to get the media information
if (rc == 0) {
// Get the duration of the media
final String duration = _flutterFFmpeg.getLastCommandOutput();
// Extract the duration from the output
final RegExp regex = RegExp(r"Duration: (\d{2}):(\d{2}):(\d{2}).(\d{2})");
final Match match = regex.firstMatch(duration);
// Calculate the duration in milliseconds
final int hours = int.parse(match.group(1));
final int minutes = int.parse(match.group(2));
final int seconds = int.parse(match.group(3));
final int milliseconds = int.parse(match.group(4));
final int durationInMilliseconds = ((hours * 3600) + (minutes * 60) + seconds) * 1000 + milliseconds;
// Return the duration in milliseconds as a string
return durationInMilliseconds.toString();
} else {
// Return an error message if FFmpeg was not able to get the media information
return "Error getting media information";
}}

}
