First flutter image displays, but not the second

Question

Problem

TMORA.png is not displaying.

Walkthrough

• Images appear here in my code:

• Error thrown by flutter:

The asset images/TMORA.png does not exist. Try creating the file or fixing the path to the file. dart(asset_does_not_exist) [51,8]

• The image does exist, though. I can see it when I click on the assets/images folder.

• I believe the problem stems from my yaml file (shown next).

• The complete code (with the TMORA.png line commented out to remove the error) appears on Github.

Note: I have two folders called images in this package. One is the project assets folder that contains an images folder with the 2 images to display on the app screen. The second is an images folder that holds images for my github readme. Am I confusing it?

• pubspec.yaml file:

name: second_app_Heather

# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

  # fonts:
  #   - family: Schyler

EDIT:

In response to @Anis R.'s suggestion (because I imagine a lot of people will suggest this), I have made an effort to implement that suggestion and recieve the following errors:

Edit #2. Respose to Anis R's 2nd helpful comment.

This was the problem... Internet resources are a little wishy-washy about where to place images that you want to use on your iPhone/android buttons, backgrounds, and other widgets. I'm not sure what is conventional/correct.

Some sources recommend placing photos inside an images folder inside the root (Orange arrow Example recommendation here). Some sources recommend placing photos inside an assets folder (Green arrow Example recommendation here- see hour 1, min 43). Some recommend placing photos inside an images folder inside the assets folder (Orange arrow - this is what I attempted).

So, when I adopted Anis R's code suggestions (which I think follow convention), I got this error message that explained what the problem was.

Now, this seems like a hard error for me to overcome. If the .yaml file can't find the assets folder, then I'm just stumped. I'm new and I don't think that I can figure this out. I have definitely seen this error before.

Where this led me was to wonder, "Well, if it can't see the assets folder, then how the hell is it displaying the museumInterior.png photo?" Both photos are located in the same folder. Or are they?

Nope. It has never been pulling images from the assets\images folder. It has no idea that the assets\images folder exists. Its been pulling pics from the images folder where I store photos for my github README.md. There's a lot of stuff in there. The image called museumInterior.png just happened to be in there too. I put a copy of the TMORA.png inside the images folder and it displays on my screen.

I, like Visual Studio Code, will pretend that assets folder, with an images folder inside, doesn't even exist.

I don't think that this is the convention, but it does run properly.

Much thanks to @Anis R. for walking me through this! Sometimes you just gotta talk it out.

Solution

In your pubspec.yaml, you should use:

- assets/images/

instead of

- images/

---

Edit regarding your update

I looked back at your code and updated comments, you need to change some code in a few places.

• First, in your Home_widget.dart, replace Image.asset('images/museumInterior.png') and Image.asset('images/TMORA.png')

with Image.asset('assets/images/museumInterior.png') and Image.asset('assets/images/TMORA.png') respectively.

• Then in your pubspec.yaml file, under assets:, only keep the entry - assets/images/ and remove the others.

• Finally, run flutter clean on your project and rebuild.

Let me know if this helps.
