Meaning

Inherited data may change, so Flutter disallows subscribing in initState. Move the read to didChangeDependencies() or build(). For a one-time read without subscribing use context.read / Provider.of(context, listen: false).

Common causes

  • Theme.of / MediaQuery.of in initState
  • Provider.of(context) with listen true in initState
  • Localizations.of in initState
  • Reading inherited widget in a constructor
  • Using context in a field initialiser

⚡ Quick fix

  1. Move the call to didChangeDependencies()
  2. Use listen: false / context.read in initState
  3. Schedule with a post-frame callback

Detailed fix by platform

Flutter

  1. @override void didChangeDependencies() { super.didChangeDependencies(); final theme = Theme.of(context); }

How to diagnose

  1. Call — In initState?
  2. Needs — Subscription or one-time read?
  3. Fix — didChangeDependencies?
