Meaning

Upgrade Flutter (flutter upgrade) or lower the dependency version/environment: sdk: range. The first line shows your current SDK version; compare it with the required range. CI may be using a different Flutter version than local.

Common causes

  • Old Flutter/Dart SDK installed
  • pubspec environment.sdk higher than installed
  • Package updated to require Dart 3
  • CI using a cached older Flutter
  • Multiple Flutter installs (FVM) with wrong version

⚡ Quick fix

  1. flutter upgrade or flutter channel stable
  2. Pin an older package version compatible with your SDK
  3. Use FVM / CI to fix the Flutter version consistently

Detailed fix by platform

Flutter

  1. flutter --version shows Dart SDK; fvm use 3.22.0 pins the project version

How to diagnose

  1. SDK — Installed version?
  2. Range — pubspec constraint?
  3. CI — Same Flutter?
