Flutter Boilerplate for Indie Hackers

Time-to-MRR is the only metric that survives indie hacking

Most indie hackers don't fail because the idea was bad — they fail because shipping idea #1 took six weeks, and by the time the paywall worked they'd already lost interest. The Flutter Kit is built around a single number: how fast can money hit your account. Email, Google, and Apple sign-in are already wired to Firebase Auth. RevenueCat is already configured with StoreKit 2 on iOS and Play Billing on Android, so subscriptions, trials, restore, and entitlement gating are a config edit — not a two-day yak-shave. You install, point it at your Firebase project, drop in your RevenueCat API keys, and the very first thing you can test is whether a stranger will pay you. That's the whole point: you're not building infrastructure, you're A/B testing demand.

What's already done so your weekend goes to the actual idea

The kit ships the plumbing every monetizable app needs, so the only code you write is the part that makes your app yours. It's all BLoC + get_it with a repository pattern, so it stays clean as you bolt on features past launch.

• RevenueCat paywalls, trials, restore and entitlement checks — flip on premium gating in minutes
• Firebase Auth (email, Google, Apple, anonymous) so users can pay the moment they sign in
• OpenAI streaming chat, DALL·E image gen and GPT-4 Vision via a Flask proxy — your API keys never ship in the bundle
• Material 3 theming with centralized design tokens — retheme the whole app from one file to match the idea
• 3 onboarding templates (Carousel, Highlights, Minimal) plus prebuilt settings and profile screens
• GA4 analytics with GDPR/CCPA consent so you can read your funnel from day one

The reuse compound: idea #2 starts where idea #1 launched

The math that makes this a no-brainer for a serial shipper isn't the first launch — it's the second. Because the license is $69 one-time for unlimited projects with full source ownership, your second app forks the codebase you already trust and skips the weekend entirely. Kill the AI module behind its feature flag if the idea doesn't need it; swap Firebase for Supabase since you own every line; restyle the design tokens and ship a totally different-looking app from the same skeleton. Indie hacking is a numbers game, and the only way to play it is to make each subsequent at-bat cheaper than the last. A boilerplate you bought once and reuse forever is exactly that — your time-to-MRR trends toward a single afternoon as your library of reusable modules grows.

When building from scratch (or FlutterFlow) is actually the right call

Be honest with yourself about the bet. If you genuinely don't know Dart yet and your goal this month is learning, building the auth and payment flows by hand teaches you more than any boilerplate — the kit is a head start, not a tutorial. If your idea is a quick throwaway prototype with no monetization, a visual builder like FlutterFlow (marketed as drag-and-drop, with its own subscription) gets a clickable demo in front of someone faster than any code-first kit. And if your app is fundamentally not a Firebase/RevenueCat shape — heavy custom backend, on-device ML, a non-subscription business model — much of what's pre-wired here is dead weight you'd rip out. The Flutter Kit wins specifically when your idea is a monetizable, cross-platform consumer or SaaS app and your bottleneck is shipping speed, not learning or prototyping.
