Following the 2.10 stable cycle, Flutter will no longer build for 32-bit iOS devices. See the RFC at flutter.dev/go/rfc-32-bit-ios-unsupported.

In rough order:

• [ci] Remove ios32 tests #97385
• flutter run -d <unsupported device> tries to run on the unsupported device #97331
• Disallow flutter run-ing on 32-bit development devices #97329
• Exclude arm7v from iOS architectures when building iOS app and plugins #97328
• Test Flutter.xcframework directory ios-arm64_armv7 or ios-arm64 #101592
• Exclude arm7v from iOS architectures when building add-to-app plugins in host app with CocoaPods #101793
• Remove 32-bit iOS builds from engine including arm7v slice of Flutter.xcframework and gen_snapshot_armv7 #97342
• b/229417378 Update ios32 paths in roll scripts
• Remove arm7v iOS logic from buildroot #97345
• When 32-bit iOS support is removed from Flutter, update the Supported platforms list website#6729
• Remove iPhone 4S devices from CI #97148

Note: excluding arm7v from plugin template/migrating existing plugins is not required, as plugins can continue supporting arm7v without impacting consuming Flutter apps.

Support for increasing minimum version from iOS 9->11 tracked separately at #101959
