How to Fix ‘Unable to Load Asset’ in Flutter

Displaying predetermined pictures from an assets folder is a must for all mobile applications. Unable to load assets is a message that Flutter occasionally shows. Consequently, we will discover how to fix Unable to load assets in Flutter in this post.

To fix the <Unable to Load Asset> error, proceed to the following steps below:

1. Go to your <pubspec.yaml> for indention errors.
2. Make sure you follow the correct <relative path> or <folder directory> where your images are located.
3. The file path format of each images in your pubspec.yaml > assets should show:

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/agent-icon/astra_icon.png
    - assets/agent-icon/breach_icon.png
    - assets/agent-icon/brimstone_icon.png
  #   - images/a_dot_ham.jpeg

4. You can also just indicate the file directory rather than indicating each of the images’ file path.

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/agent-icon/
    - assets/Agents/
  #   - images/a_dot_ham.jpeg

• Inside the pubspec.yaml, make sure to use proper indention, DO NOT USE ‘TAB‘.

5. Use the full file path when using the image. ‘./<main file folder>/<relative file folder>/<image.'image type'>‘.

              AgentTile(
                agentImagePath: './assets/agent-icon/astra_icon.png',
                agentName: 'Astra',
                agentType: 'Controller',
                agentAbout: 'About',
              ),
              AgentTile(
                agentImagePath: './assets/agent-icon/breach_icon.png',
                agentName: 'Breach',
                agentType: 'Initiator',
                agentAbout: 'About',
              ),
              AgentTile(
                agentImagePath: './assets/agent-icon/brimstone_icon.png',
                agentName: 'Brimstone',
                agentType: 'Controller',
                agentAbout: 'About',

6. In your terminal, type in <flutter clean>.
7. Then lastly, restart your your Emulator.
