After a few headaches, I'm now able to run both Claude Code and Flutter within a sandboxed dev container. This is great for both safety 🛡️ and speed 🚀 Here's a detailed guide with my complete setup (source code included) 👇 codewithandrea.com/articles/run...

Spent the whole day dockerizing my coding setup so I can safely run `claude --dangerously-skip-permissions` and mitigate damage if things go wrong. Many gotchas along the way. I'll try to share an article once I get it working properly.

The more I use AI for coding, the more I realize how powerful it is. But I still feel like a beginner and I now see a long road to real mastery. My new plan: - I'll dive deeper and aim to get really good at this - Once I'm ready, I'll start sharing new content

Kinda wanted to have a play with Antigravity today, but...

Just managed to one-shot a video transcription CLI tool (3000+ LOC including tests). How I did it: - Written a detailed spec (with some help from AI) - Used my own custom /plan and /work sub-agents Claude code did all the work -> AI Agents are getting better! Quick demo 👇

So much cool stuff happening in AI right now, especially for us developers! Just tested Antigravity with Gemini 3 Pro. 💻 Very nice... but I still miss a few things from Claude Code. Will publish a video next week!

Been doing some tweaks and polish on my currency converter app. I built >90% of it with agentic AI and I'm improving my workflows as I go along. Check it out here: currency-converter-ab.web.app

Code it yourself, or prompt the AI? 🧐 That's a very valid question, since AI doesn't always get it right. In my latest video, I offer insights from my experience, along with a decision matrix that will help you save time and avoid frustration. Watch it here 👇 youtu.be/HOhYX9lA6T8

When to Code vs Prompt with AI

YouTube video by Andrea Bizzotto

youtu.be

When coding with AI, I follow a fairly simple principle: If prompting effort > coding effort, code it. 😅 Would it be useful if I made a video with examples, etc?

Effort to code vs Effort to Prompt: my 2x2 matrix

1. Low prompt, Low code
- Small UI/animation tweaks
- Pull to refresh
- Codegen
- Simple refactors
2. High prompt, Low code
- Line-level instructions
- Dense business logic
- One-line bug fixes
- Layout errors (overflows, unbounded heights, etc)
3. Low prompt, High code
- Boilerplate (crash reporting, analytics setup)
- Writing tests
- Localization
- Theming system
- Big refactors (AI usually does this in multiple steps + run analyzer ... can be slow)
4. High prompt, High code
- Offline caching + syncing
- Full-stack features
- Background tasks + iOS/Android specific
- Complex charting solutions
- IAP + entitlements

For 1 and 2, use Autocomplete and IDE assists.
For 3 and 4, use AI agents for planning, implement in stages, consider verification effort.

Back in the day, many companies used to under-promise and over-deliver, leading to customer satisfaction and long-term business prospects. Sad to see late-stage capitalism changed this. Now it seems to be the norm (esp. for AI companies) to trick customers and do the opposite.

Super interesting new podcast with Andrej Karpathy!👇 www.dwarkesh.com/p/andrej-kar...

This is kinda how I build with AI these days. Same for you?

Today I built the currency conversion charts for my new app. Or rather, I wrote the spec, and CC Sonnet 4.5 did all the planning and implementation. 🚀 Got it all done in ~4 hours, even though I wasn't at all familiar with the fl_charts library. Very impressed!

Did you know? You can use absolute imports for reusable Dart files that are copy-pasted across projects. This way, they are always imported correctly (as long as they live in the same location relative to the project root).

If you copy-paste Dart files to a new project, your imports will fail:
import 'package:old_app/src/constants/layout_breakpoints.dart';

You can Find & Replace package:old_app with package:new_app to fix them (annoying and not very scalable)

Alternatives

Relative imports:

import '../../constants/layout_breakpoints.dart';

Absolute imports:

import '/src/constants/layout_breakpoints.dart';

Absolute imports are handy for files that always live in the same location across multiple projects (e.g. /src/constants)

Consider this as a temporary solution. Reusable files should be moved into a common package (works best with monorepo setups).

Very interesting post-mortem from Anthropic about the recent reliability issues: www.anthropic.com/engineering/...

A postmortem of three recent issues

This is a technical report on three bugs that intermittently degraded responses from Claude. Below we explain what happened, why it took time to fix, and what we're changing.

I'm testing Codex with GPT-5 for my new app. Haven't tested any complex use cases yet, but so far it seems on par with Claude Code (and quite a bit cheaper to run). Want a video about it? Like/let me know in the comments.

I started a new side project. 🚀 Goal: build a simple currency converter app that doesn't suck, using Claude Code & other AI tools. Here's a very early build (which sucks but it'll get better): currency-converter-ab.web.app
