Kiling it Dimitar. Awesome stuff. How do we allow multiple file types?

[@lugwirelouis1574]

Great video but how do you retrieve the image to the client side like a social media app

[@flutterflowexpert]

When you upload the file you will get a URL you can use that URL to display the image after that.

[@harijella7867]

Great video to update and upload the document. Can you show how to View/Display the pdf/zip/doc/text from the Fire Storage?

[@flutterflowexpert]

When you say Display what do you exactly mean as those are 4 different types of that and they are all displaying differently.

How do you use choicechips in a form to send a list of document references to Firebase?

[@flutterflowexpert]

What do you mean? You want when the choicechip is selected to send the data then or?

[@ChrisLaupama]

@@flutterflowexpert Let’s say I have three collections. Users, Posts and Groups. Users collection has a field of List>Groups ( which is an array of Group document references ) - this represents all of the groups this User is a member of. Then, in Posts I have a field of List>Groups ( which is an array of Group document references ) - this represents which Groups this post can be displayed in In the form, I connect the User collection and map the list of Groups to the ChoiceChips ( this part I’ve managed to do ) so now the choicechips are displaying each group the user is a member of. But then, when the user selects the choice chips, I want to post to Firebase the choicechips that have been selected in the form to Post List>Group field. How would I do this?

Hello, I did everything to the letter but I could not do it. The code you share is different from the one you are using in the example and it doesn't work. It's a shame to waste so much time to get nowhere.

[@flutterflowexpert]

The code is optimized. Why is it not working for you? Please join the Discord channel and let me know what is the issue - discord.gg/ERDVFBkJmY

[@nordoow3404]

It's a fantastic job so far! Perhaps, with your code, it could be possible to check the file size before uploading to Firestore, a functionality not available in the native upload functions from FlutterFlow. Could you please consider adding code that enables us to retrieve the file size before uploading? This would allow us to implement a file size limit...

[@flutterflowexpert]

Yes I will think about improving this code. Good suggestion.

Hey i watched your video. I am new to FF. Actually I've created a Dashboard page where there is list view and table. I want when user click on Upload button, it should save that data to firebase and return me a url so that i can give that url to Zapier web hook to perform furthur step

[@flutterflowexpert]

yeah you can totally do that and this code will return you the url of the file that was saved in FB Storage

[@СергейАбрамов-и3т]

Hello! When I try to run test mode it shows an error - could not find directory like ...flutter_flow/upload_media.dart. I tried to change path but it is the same

[@flutterflowexpert]

the code is now changed. the new code is import '../../flutter_flow/upload_data.dart'; github.com/bulgariamitko/flutterflowtutorials/blob/main/Custom%20Actions/upload-any-file-type.dart

[@СергейАбрамов-и3т]

​@@flutterflowexpert Thank you! As for "upload_data.dart'" - is this file that already implemented in FF backend? How can I see classes and methods for example?

[@flutterflowexpert]

@@СергейАбрамов-и3т You can download the source code and then you can see all the classes and methods FF is using.

[@apoorvsaxena3886]

is it possible to upload any filetype without giving the filetype as an argument in the custom function ? without specific filetype ?

[@flutterflowexpert]

no it is not. You need to list all fileTypes and it should be String of arrays like ['pdf', 'png'...]

[@apoorvsaxena3886]

@@flutterflowexpert Thanks :) Awesome videos

[@sheldontroll]

how can i store it on the local state so i can upload the file with another information on my FF document?

[@flutterflowexpert]

What do you mean?

[@sheldontroll]

@@flutterflowexpert im trying to register an user but this user has to upload a pdf, so i wanna store the file until i press a button to register the user on my Firebase db

[@flutterflowexpert]

​@@sheldontroll So you want to store a file before a user is registered or logged in?

[@sheldontroll]

@@flutterflowexpert before is registered, and save it with the registration of the user document in firebase

[@flutterflowexpert]

@@sheldontroll if it is before it is registered then I guess you can save it in a variable, I mean the file, and when the user registered to upload it to firebase.

[@Christian-cl2fw]

thanks for your content! I use flutterflow myself and have small problem. I build a price feed (stocks) and do an API call to get the price change of a stock f.e. amazon. Afterwards I run a custom function to convert this data into a string so I do display a format like -0.45% This works fine. But I want to set the color to green, if it is a positive number or to red in case it is negative. I am trying to find a solution for weeks now, nothing works. Could you help me? :))

Can you upload a website file or maybe code?

[@flutterflowexpert]

[@awakening2dream]

How can be implemented a realtime virus and malware scanning when uploading a file?

[@flutterflowexpert]

You need to first send the file using an API to check it for viruses and then store it in Firebase or you can store it then check it and if there are viruses, delete the file.

[@charliefinale]

One correction to the code, you should add a ! to this line so it becomes final selectedFile = await selectFile(allowedExtensions: [fileType!]); Also I believe we can refactor the imports so that it will compile in FF. I will try. Otherwise great code that I have tested and it works.

[@flutterflowexpert]

Thanks for your comment. This is used for null safety and you can have this line for that fileType = fileType ?? 'pdf'; So you don't need '!'. Also for the code it will not compile because of how FF was built. It should compile, but it will not. In the feature FF team will fix that.
