Final String Widget Demo Workflow

This shows how to set up a workflow to test the final_string widget functionality:

┌─────────────┐    ┌─────────────────────────┐    ┌─────────────┐
│ Load Image  │    │ Gemini Image Describe   │    │ Show Text   │
│             │────▶│                         │────▶│             │
│ [Load your  │    │ - API Key: [your key]   │    │ Displays    │
│  test image]│    │ - Model: gemini-2.5-    │    │ final       │
│             │    │   flash                 │    │ generated   │
└─────────────┘    │ - System Prompt: [...]  │    │ prompt      │
                   │ - User Prompt: [...]    │    └─────────────┘
                   │                         │
                   │ ┌─────────────────────┐ │
                   │ │ final_string widget │ │  ← This widget will
                   │ │ (will auto-update)  │ │     populate after
                   │ └─────────────────────┘ │     execution!
                   └─────────────────────────┘

Step-by-step Instructions:

1. Import the workflow:

   • Copy the contents of example_workflow.json
   • In ComfyUI, go to "Load" → "Load (from file)" or drag the JSON file

2. Set up the nodes:

   • Load Image: Choose any test image
   • Gemini Image Describe: Enter your valid Gemini API key
   • Show Text: This will display the final output

3. Execute the workflow:

   • Click "Queue Prompt" to run the workflow
   • Wait for the Gemini API to process the image

4. Check the results:

   • The final_string widget on the Gemini node should populate with generated text
   • The Show Text node should display the same text
   • Browser console should show "Updated final_string widget with:" message

What was fixed:

• ❌ Before: final_string widget showed placeholder text
• ✅ After: final_string widget shows actual generated description

The widget update happens automatically when the node execution completes!
