Lower minimum Flutter SDK to 3.22.0 and Dart to 3.4.0#1704
Merged
Conversation
The minimum versions were raised to Flutter 3.27.0 / Dart 3.6.0 as part of the v9.0.0 release, but neither the web support (package:web ^1.1.1 requires only Dart ^3.4.0) nor the freezed removal technically required those versions. This lowers the floor to allow users on older Flutter versions to use the SDK. Changes: - pubspec.yaml: sdk >=3.4.0, flutter >=3.22.0 - purchases_ui_flutter/pubspec.yaml: same - .circleci/config.yml: min version CI jobs test against 3.22.0 - CLAUDE.md, AGENTS.md, DEVELOPMENT.md: updated version references Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

These always run using flutter:stable instead of the min version we support, should we update these as well to keep them in sync?

I think this is intentional so we also test against the latest flutter version released. We could potentially add separate tests to run against the min version... But I think the min sdk versions that already exist are enough? Happy to chat more if you think we need those though!

Discussed over Slack; we'll expand these to cover both the latest and min version in a follow up PR

…1707) Follow-up to #1704 which lowers the minimum Flutter SDK to 3.22.0. ## Summary Parameterize CI lint and test jobs to run against both `flutter:stable` and the minimum supported Flutter version (3.22.0). Replaces the old `test_main_sdk_min_version_compatibility` and `test_ui_sdk_min_version_compatibility` jobs which only verified dependency resolution. | Job | Flutter | What it does | |-----|---------|-------------| | `lint-test` | stable | analyze + test root SDK | | `lint-test-min-version` | 3.22.0 | analyze + test root SDK | | `lint-test-ui` | stable | analyze + test UI SDK | | `lint-test-ui-min-version` | 3.22.0 | analyze + test UI SDK | | `lint-sample-apps` | stable | resolve deps for example apps + api_tester | ## Test plan - [x] All CI jobs pass - [x] Min version jobs correctly use Flutter 3.22.0 - [x] Update required job list <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Low risk: CI-only changes that adjust which CircleCI jobs run and which Flutter Docker images they use; main risk is longer runtimes or unexpected CI failures due to running tests on Flutter 3.22.0. > > **Overview** > Updates CircleCI to run **lint + unit tests** for both `purchases_flutter` and `purchases_ui_flutter` against `flutter:stable` and the minimum supported Flutter version (`3.22.0`) via parameterized `lint-test` and `lint-test-ui` jobs. > > Replaces the old min-version compatibility jobs (which only resolved dependencies) with a new `lint-sample-apps` job for dependency resolution of sample apps/`api_tester`, and simplifies jobs by removing the unused `build-flutter-project` command and using `flutter-get-dependencies` directly in integration test steps. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit ff2b112.

Note
Medium Risk
Moderate risk because it expands the supported toolchain and could surface incompatibilities with older Flutter/Dart versions despite passing CI. Changes are limited to version constraints, CI configuration, and documentation.
Overview
Lowers the minimum supported SDK versions to Flutter 3.22.0 and Dart 3.4.0 by updating the
environmentconstraints in bothpubspec.yamlfiles.Updates CI’s minimum-version compatibility jobs to run against Flutter
3.22.0, and aligns developer documentation (AGENTS.md,DEVELOPMENT.md) with the new support policy.Written by Cursor Bugbot for commit 3bf8e6c. This will update automatically on new commits. Configure here.
