🚀 **New Tool: Riverpod 3.0 Safety Scanner**

I just published a static analysis tool for detecting Riverpod 3.0 async safety violations!

**Install:**
```bash
pip install riverpod-3-scanner
riverpod-3-scanner lib
```

**Why I built this:**
After experiencing 47 production crashes in 3 days from a single unmounted ref violation, I created a comprehensive scanner that detects 14 types of async safety issues.

**Features:**
✅ Zero false positives (4-pass call-graph analysis)
✅ Detects lazy getters, field caching, missing mounted checks, ref in lifecycle callbacks
✅ CI/CD ready (pre-commit hooks, GitHub Actions)
✅ 1,100+ lines of documentation with real crash case studies

**Results:** Went from 12+ crashes/week to zero for 30+ days.

## 📣 Reddit r/FlutterDev Post

**Title:**
```
[Tool] I created a static analyzer for Riverpod 3.0 that prevented 47 production crashes - now on PyPI
```

**Body:**
```
After experiencing multiple production crashes from unmounted provider references in my Flutter app (47 crashes in 3 days!), I built a comprehensive scanner that detects 14 types of Riverpod 3.0 async safety violations.

## Install

```bash
pip install riverpod-3-scanner
riverpod-3-scanner lib
```

## The Problem

Riverpod 3.0 added `ref.mounted` to handle async safety, but it's easy to miss checks. Common crash patterns:

❌ Lazy getters in async classes
❌ Missing `ref.mounted` after `await`
❌ `ref.read()` inside `ref.listen()` callbacks
❌ Sync methods with `ref.read()` called from async callbacks

## What It Does

- 🔍 Detects 14 violation types with zero false positives
- 📊 Uses 4-pass call-graph analysis (traces method calls across files)
- 🎯 Resolves variables to classes (knows `basketballNotifier` → `BasketballNotifier`)
- 📚 Provides detailed fix instructions for each violation
- 🚀 CI/CD ready (exit codes, pre-commit hooks)

## Real Impact

**Before:** 252 violations, 12+ crashes/week
**After:** 0 violations, 0 crashes for 30+ days

## 📣 LinkedIn Post

```
🎉 Excited to share our latest open-source contribution!

After experiencing 47 production crashes in just 3 days from Riverpod async safety issues, I built a comprehensive static analysis tool to prevent these crashes.

Today, I'm open-sourcing it on PyPI! 📦

**riverpod-3-scanner** detects 14 types of Riverpod 3.0 violations using sophisticated call-graph analysis:

✅ Zero false positives
✅ Cross-file violation detection
✅ Detailed fix instructions
✅ CI/CD ready

**Real Impact:**
• Detected 252 violations in our 200k-line Flutter codebase
• Reduced crashes from 12+/week to ZERO for 30+ days
• Now helping the Flutter community avoid similar issues

**Install:**
pip install riverpod-3-scanner

Built at DayLight Creative Technologies while developing SocialScoreKeeper. Open source (MIT) and ready to use.

Show HN: Static analyzer for Riverpod 3.0 async safety (prevented 47 crashes)

```

**Comment to add:**
```
Author here. I built this after experiencing 47 production crashes in 3 days from a single Riverpod async safety violation (lazy getter in async class).

The tool uses 4-pass call-graph analysis to detect 14 violation types with zero false positives. It traces method calls across files, resolves variables to classes, and detects sync methods called from async callbacks.

Real impact: Fixed 252 violations in our 200k-line Flutter codebase, went from 12+ crashes/week to zero for 30+ days.

Just published to PyPI: `pip install riverpod-3-scanner`

Happy to answer questions about the call-graph analysis, false positive prevention, or the production crashes that motivated this.
