I Built and Published a Flutter + Claude API Guide Using AI to Help Write It — Here's What I Learned

Meta but true: I used Claude to help me research and structure a guide about integrating Claude into Flutter apps.

The guide covers everything I wish existed when I started:

• Package setup (anthropic_sdk_dart — pure Dart, works on all platforms)
• API key security across dev, staging, and production
• Streaming responses token-by-token into Flutter UI
• Multi-turn conversation history management
• A complete drop-in AI chat widget (copy-paste ready)
• Error handling for production
• What's next: tool calling, extended thinking, Genkit Dart

All code verified against the live Anthropic API docs. ~40 pages.

If you're a Flutter dev who wants to ship AI features without spending a weekend figuring out the plumbing — this is for you.
