Keep a Flutter WebView on your own domain with webview_flutter 4.14.1: parse the URL, compare Uri.host instead of startsWith, hand mailto: and tel: to url_launcher, and know what Android and iOS actually send to onNavigationRequest.

Run a Flutter location tracker that survives the Home button, a swipe from recents and a reboot on Android 15 and 16: a location-typed foreground service in its own Flutter engine, the exact permissions, and the SecurityException you get when the while-in-use rules bite. Tested with geolocator 14.0.3 and flutter_foreground_task 11.0.3.

The full path from an AGP 8 Flutter app that applies kotlin-android to AGP 9.1 with android.builtInKotlin=true on Flutter 3.47. Every step was built and measured, including the two edits that look optional and are not: kotlinOptions is a compile error under KGP 2.2+, and the KGP line in settings.gradle.kts has to stay.

describeEnum has been deprecated since Flutter 3.16 and its removal PR is approved. How to replace every call with Enum.name (Flutter 3.47.4, Dart 3.13), handle enum-like classes and diagnostics, find the calls hiding in dependencies like flutter_svg 1.x, and what the build error looks like once it is gone.

Xcode 27 refuses to build anything below macOS 12, and Flutter 3.47 moved its own floor from 10.15 to 12.0. What the automatic migration rewrites, the three places it silently skips (custom values, Podfile post_install overrides, plugin podspecs), and a Podfile fix for teams still on Flutter 3.44.

Ship skwasm with flutter build web --wasm when your dependencies compile to Wasm: it downloads less and rendered 36% more frames than CanvasKit on a heavy scene. On Flutter 3.47.x, keep it single-threaded until the multi-threaded text crash fix leaves beta.

Flutter 3.47.0 cannot parse adb rows whose serial is 22+ characters, so wireless and some USB Android devices vanish. Upgrade to 3.47.1 or later, or adb connect by IP.

cmdline-tools 23.0 retired sdkmanager --licenses, so Flutter before 3.47.3 reports license status unknown. Upgrade Flutter, or pin cmdline-tools 22.0.

Flutter web 3.41 to 3.44 reports a ~625x line-height override when an Android WebView's textZoom is not 100. Upgrade to 3.47, or clear the override in MaterialApp.builder.

A reload only revalidates index.html, so an unhashed main.dart.js keeps coming from the browser cache. Send Cache-Control: no-cache for the Flutter build output, stamp a build id where you cannot set headers, and let the self-cleaning service worker retire pre-3.41 caches.
