Flutter (Android): java.io.IOException: Cleartext HTTP traffic to api.example.com not permitted
Android 9+ blocks plain `http://` requests by default; the app must use HTTPS or explicitly allow cleartext for that host.
Flutter iOS: Error running pod install — CocoaPods not installed or out of date / [!] CocoaPods could not find compatible versions for pod
The iOS build cannot install its native dependencies because CocoaPods is missing, outdated or a pod's version constraints confli…
Android Gradle: Execution failed for task ':app:checkDebugAarMetadata'. Dependency requires libraries and applications that depend on it to compile against version 34 or later of the Android APIs
A dependency was built against a newer Android API than your project's `compileSdk`.
Flutter: dependOnInheritedWidgetOfExactType<_InheritedTheme>() or dependOnInheritedElement() was called before _HomeState.initState() completed
`Theme.of(context)`, `MediaQuery.of(context)` or `Provider.of(context)` was used in `initState`, where inherited widgets are not…
flutter doctor: Android license status unknown. Run `flutter doctor --android-licenses` to accept the SDK licenses
The Android SDK licenses have not been accepted, so builds cannot download or use SDK components.
flutter doctor: Android SDK is missing command-line tools; download from https://goo.gl/XxQghQ — cmdline-tools component is missing
The Android SDK Command-line Tools package is not installed, so Flutter cannot run `sdkmanager` or accept licenses.

The device or emulator doesn’t have enough free internal storage to install the APK.

Provisioning profile "x" doesn't include the currently selected device
The development profile doesn’t list this iPhone’s UDID, so Xcode can’t install the build on it.
Signing for "App" requires a development team. Select a development team in the Signing & Capabilities editor
No Apple developer team is selected for the target, so Xcode can’t sign the app.
Swift: No such module 'X' (module not found)
Xcode can’t find a Swift package, pod or framework you import.
Android: INSTALL_FAILED_UPDATE_INCOMPATIBLE
An app with the same package name but a different signing key is already installed on the device.
INSTALL_FAILED_TEST_ONLY: installPackageLI
The APK is marked testOnly (built by Android Studio’s Run button), so normal installs refuse it.
adb server version (41) doesn't match this client (39); killing...
Two different adb binaries are running — e.g. Android Studio’s SDK adb and another one on PATH (Homebrew, Genymotion, older SDK).
Failed to register bundle identifier: The app identifier "com.x" cannot be registered to your development team because it is not available
Another developer team already owns that bundle identifier, so Xcode can’t create it for your team.
Provisioning profile "x" doesn't include signing certificate "Apple Development: Name (ID)"
The profile was created with a different certificate than the one installed in your keychain.
Command CodeSign failed with a nonzero exit code (errSecInternalComponent / resource fork, Finder information not allowed)

ActivityNotFoundException: Unable to find explicit activity class; have you declared this activity in your AndroidManifest.xml?
An Intent targets an Activity that isn’t declared in the manifest, or an implicit intent has no app to handle it.

A FragmentTransaction (or DialogFragment.show/navigation) ran after the Activity saved its state, typically from an async callbac…
IllegalStateException: Fragment x not attached to a context / not attached to an activity
Code called requireContext()/requireActivity()/getString() after the Fragment was detached — usually in an async callback.
Jetpack Compose: Vertically scrollable component was measured with an infinity maximum height constraints, which is disallowed
A LazyColumn (or verticalScroll) is placed inside another vertically scrolling container, so it gets infinite height.
Flutter: A RenderFlex overflowed by x pixels on the right/bottom
A Row or Column’s children need more space than available, so Flutter draws the yellow-black overflow stripes.
Flutter: RenderBox was not laid out: RenderFlex#a1b2c relayoutBoundary=up2 NEEDS-PAINT — Failed assertion: 'hasSize'
A widget was asked for its size or painted before layout finished, usually because a parent gave it unbounded or conflicting cons…

An async callback (network, timer, stream) finished after the widget was removed and then called setState.
Flutter: Looking up a deactivated widget's ancestor is unsafe. At this point the state of the widget's element tree is no longer stable
You used a `BuildContext` after its widget was removed from the tree — typically after an `await` when the user already navigated…

Google Sign-In failed on Android because the app's SHA-1 fingerprint or package name is not registered for the OAuth client.
Android Gradle: uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [:firebase_auth]
A plugin requires a higher Android minimum SDK than your app declares.
Dart pub: The current Dart SDK version is 2.19.0. Because app requires SDK version >=3.0.0 <4.0.0, version solving failed
A package (or your own pubspec) requires a newer Dart SDK than the one your Flutter installation provides.
