I have a series of images stashed in Assets. I want to be able to select which image is displayed, dynamically. How would you do this?
Longer-version...
I have 100 items in an SQLite DB, each item has a name, some description, and the filename of an associated image (~100px) that is in my project's Assets. I am able to query the SQLite DB and have fields like Name and Description be populated dynamically. My struggle is with getting the image to display dynamically.
I simplified everything to bare-bones:
a Read Query that only returns two columns: description & imageFilename.
(For imageFilename I tried type String, and type Image Path, doesn't seem to matter)
a new, blank page, added a single parent, with child widgets of text and image
On the parent I have my SQLite query
(I've tried Column, Row, and ListView as the parents, makes no odds)
On the text widget..
content shows imageFilename (when I tried the SQL Query output Type as String), and then later showed Cues (when I was trying imageFilename as Type: Image).
I can see the content, and the content is as I would expect, so I believe the SQL Query is setup correct and the backend query is setup correctly.
On the image widget...
I first set Image Type: Asset, and used the manual picker to find the image file associated with my example case. That displayed fine, so I know the image asset is physically there, and able to be displayed on this screen.
I then switched to Image Type: Network in order to allow me to pass a variable to the location. When I try that, I don't get an error in the FF builder, but where the Image Widget should be, I instead see:Invalid Argument(s): No host specified in URI file:///assets/images/<my-filename-would-go-here.jpg>
As well as assets/images, I also tried just the filename, and the full actual path on the device.../data/data/com.xxxx.yyy/code_cache/zzz/build/flutter_assets/assets/images/
but still no joy.
So, I clearly need help. Ideas? Am I missing something obvious? Or am I going to need to write a custom image widget to display a file-from-device dynamically?
