[various] Update READMEs to reflect current OS support (#10470)

stuartmorgan-g · web-flow · commit 8168d9c856a1 · 2025-11-26T20:26:14.000Z
* Updates all READMEs to list the OS versions currently supported by the latest platform implementations. * This is not necessarily the same as the OS version that the current version of the app-facing platform supports; for plugins where the app-facing package still supports Flutter 3.32, clients using Flutter 3.32 will get older versions of the platform implementations that are still compatible with iOS 12/Android API 21-23. However, the Flutter team no longer actively supports those versions, which is what we are choosing to reflect in READMEs. (In the future, we may want to move this information to platform implementation package READMEs, although that will make it harder to skim.) * Updates all Android plugins that still listed a `minSdkVersion` of 21 to 24. * This is a no-op for clients; all of these implementation packages already require Flutter 3.35, which can only build for 24+. * This part is the Android version of #10231, but no SDK changes were needed here. All the changes where we could make code changes were already done in #9851. Fixes flutter/flutter#178757 ## Pre-Review Checklist [^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
