How to reserve space for an adaptive AdMob banner in Flutter to avoid layout shift

The official google_mobile_ads sample renders nothing until onAdLoaded, so your content jumps by 150 dp seconds after the screen appears. Ask for the anchored adaptive size first, reserve it with a SizedBox, persist the height across launches, and only then load the ad. Measured on Flutter 3.44.8 with google_mobile_ads 9.1.0.

Fix: Android status bar icons become unreadable after enabling UseMaterial3 in .NET MAUI 10

MAUI 10.0.100 picks status bar icon colors from colorPrimary, which is the opposite brightness of the Material 3 surface, so you get white on white or black on black. Update Microsoft.Maui.Controls to 10.0.101 or later, or reset AppearanceLightStatusBars in MainActivity.

Fix: MediaPicker.CapturePhotoAsync returns a PNG instead of a JPEG in .NET MAUI 10

On iOS, MAUI 10 re-encodes camera photos as PNG whenever CompressionQuality is 90 or higher and no MaximumWidth/Height is set, which includes the default. Set CompressionQuality to 89 or lower, or add a MaximumWidth on iOS only.

How to block a Flutter WebView from navigating to external URLs with NavigationDelegate

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.

How to keep Flutter location tracking running in the background on Android 15

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.

Migrate a Flutter Android project to AGP 9 with built-in Kotlin

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.

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.
