Act as a senior Flutter engineer + GIS/map system expert (ArcGIS-like SDK).
|
||
|
|
|
||
|
|
## Context
|
||
|
|
I am a non-technical developer using AI to build a map-based app (Flutter + Map SDK).
|
||
|
|
|
||
|
|
This feature involves:
|
||
|
|
- Map rendering
|
||
|
|
- Layer loading
|
||
|
|
- Dynamic property application (styling / behavior)
|
||
|
|
|
||
|
|
There is a bug, and previous AI fixes made the system more complex.
|
||
|
|
|
||
|
|
I do NOT understand:
|
||
|
|
- How map SDK handles layers internally
|
||
|
|
- When properties are applied (before/after render)
|
||
|
|
- Full data flow across UI → logic → SDK
|
||
|
|
|
||
|
|
You MUST first explain system clearly before fixing.

## Output Format (STRICT)
|
||
|
|
|
||
|
|
### 1. Map System Flow (Visual + Layer-Specific)
|
||
|
|
|
||
|
|
#### A. Flow Diagram
|
||
|
|
Provide a real flow diagram based on the given feature and code, showing:
|
||
|
|
- User action
|
||
|
|
- UI layer
|
||
|
|
- Controller/state handling
|
||
|
|
- Layer creation
|
||
|
|
- SDK interaction
|
||
|
|
- Property application
|
||
|
|
- Rendering
|
||
|
|
- UI update
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
#### B. Explain Each Stage
|
||
|
|
Explain clearly:
|
||
|
|
- What happens at each step
|
||
|
|
- What data is passed between layers
|
||
|
|
- What the SDK is likely doing internally
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
#### C. Critical Timing Points (IMPORTANT)
|
||
|
|
Identify:
|
||
|
|
- When the layer is created
|
||
|
|
- When data is loaded from source
|
||
|
|
- When properties SHOULD be applied relative to SDK lifecycle
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
### 2. Expected Behavior (Map-Specific)
|
||
|
|
Define expected behavior based on inputs:
|
||
|
|
- Successful layer load
|
||
|
|
- Correct property application
|
||
|
|
- Failure scenarios (invalid input, missing data, SDK failure)
|
||
|
|
|
||
|
|
If unclear, ask up to 3 specific questions and STOP.
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
### 3. Current Behavior
|
||
|
|
Explain what is actually happening using:
|
||
|
|
- The provided issue description
|
||
|
|
- The given code
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
### 4. Mismatch (Critical)
|
||
|
|
Identify exactly:
|
||
|
|
- Where expected behavior differs from actual behavior
|
||
|
|
- Which step in the flow is failing
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
### 5. Root Cause (Precise)
|
||
|
|
Identify the exact reason for the bug:
|
||
|
|
- Timing issue
|
||
|
|
- Incorrect layer reference
|
||
|
|
- State not updating
|
||
|
|
- Async handling issue
|
||
|
|
|
||
|
|
Point to specific function, block, or lifecycle stage in the code.
|
||
|
|
|
||
|
|
If unsure, clearly state assumptions.
|
||
|
|
|
||
|

|
||
|
|
|
||
|
|
### 6. Minimal Fix (STRICT)
|
||
|
|
- Provide the smallest possible change
|
||
|
|
- Do NOT rewrite the system
|
||
|
|
- Provide ONLY the modified code snippet
|
||
|
|
|
||
|
|
Focus on:
|
||
|
|
- Fixing timing
|
||
|
|
- Correcting data flow
|
||
|
|
- Fixing state updates
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
### 7. Why Fix Works
|
||
|
|
Explain how the fix resolves the issue:
|
||
|
|
- Link it to the system flow
|
||
|
|
- Link it to SDK behavior
|
||
|
|
- Link it to timing/lifecycle
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
### 8. Map-Specific Risks (IMPORTANT)
|
||
|
|
Analyze:
|
||
|
|
- Impact on other layers
|
||
|
|
- Performance implications
|
||
|
|
- Possible re-render issues
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
### 9. Prevention (Map Architecture)
|
||
|
|
Suggest improvements:
|
||
|
|
- Better layer lifecycle handling
|
||
|
|
- Proper placement of property logic:
|
||
|
|
- Config layer
|
||
|
|
- Renderer
|
||
|
|
- Controller
|
||
|
|
|
||
|
|
---
|
||
|
|
|
||
|
|
## Constraints
|
||
|
|
- Do NOT assume SDK behavior without stating it
|
||
|
|
- Do NOT move logic randomly
|
||
|
|
- Do NOT add conditions blindly
|
||
|
|
- Focus on timing and data flow
|
||
|
|
|
||
|

|
||
|
|
|
||
|
|
## Fallback Rule
|
||
|
|
If inputs are insufficient:
|
||
|
|
- Ask up to 3 specific questions
|
||
|
|
- STOP and wait for clarification
|
||
|
|
|
||
|

|
## Self-Check
|
||
|
|
Before answering:
|
||
|
|
- Did I map the bug to a specific flow step?
|
||
|
|
- Did I identify a timing issue if present?
|
||
|
|
- Is the fix minimal and scoped?
|
||
|
|
- Did I avoid over-engineering?
