I want to overlay a caption to different sorts of media (images, gifs, videos). Essentially add a white bar on top or bottom of the image and then write in some text. Then save the image/video to firebase as a new image with the caption added to it.
Does anyone know of any useful packages or tutorials that could help me do this?
There are some dart packages I can list so that they will help you:
Image editor pro
For storing them in firebase i can list you another package:
Firebase picture uploader

In my Flutter app, I want to be able to create some kind of certificate of completion. The layout will be always the same, but picture and text in it should change. This certificate should be created in a jpg format, so I can share it with other apps.
Does anyone have an idea how this could be accomplished?
The only way I can imagine is that I create a Screen template where I put in text and picture, then let the phone take a screenshot and save that screenshot automatically. But this might lead to unwanted content in the picture and different image sizes. I have searched for Widgets/ ways to create an image in Flutter but could not find anything.
You will need to create a widget with constructors (Image and text).
Then use a flutter package called screenshot to capture the parent widget as image and save it to the users phone.

I upload the pdf file from storage.
I'm trying to place the signature image at the bottom of every single page of pdf file and save as new pdf file using flutter.
I don't know how to do that? I tried my sample but I didn't find the solution I wanted. Please suggest me any flutter plugins or packages.
The idea is very simple: it consists of reading the pdf file as images
(one image per page), and then create a pdf, having as background one
of the retrieved images.

I have used a decorative image in my Flutter image using the Image class.
When I use Android Talkback to hover over the image it says "unlabelled image", is there a way to remove this description so nothing is announced?
The Android docs have guidance on removing it for Android, how should I do this in Flutter?
Decorative images or images that don't convey meaningful information
graphically do not require content labels. In these cases, set an
android:contentDescription attribute of "#null" or an
android:importantForAccessibility attribute of "no".
Trying to make my own progressing/loading message dialog by keeping an animated image like GIF in it. But, its not working.
Can any one help me how to use the animated images in Smartface app studio.

Up to now, only png files were being used to show icons in Smartface.
But, with the new release (4.5.0), "Assets" folder will be in use. You will be able to place different kind of files inside this folder, and you can reach them such as below :
