Flutter: Difference between revisions
imported from old wiki (The second flake example doesn't work because it uses a variable androidSdk which is defined in the flake before it, but not the second one) |

* The default Gradle template for android captures the Android and Flutter SDK paths in <code>android/local.properties</code> preventing future updates to the SDK from participating in the build. Example:<syntaxhighlight lang="shell-session">$ cat android/local.properties | |||
sdk.dir=/nix/store/m5ygjwkz8brwkw9anx9kbwssymwvlaxl-androidsdk/libexec/android-sdk | |||
flutter.sdk=/nix/store/rga4z7r7x705lns431b89gwxx47zs1zp-flutter-wrapped-3.29.3-sdk-links | |||
flutter.buildMode=debug | |||
flutter.versionName=6.3.2</syntaxhighlight>This manifests itself as Gradle failing to install SDK components registered in the shell. To fix, simply delete the properties file and run the build again. NOTE: this assumes that the shell correctly reflects the requirements of the build. If it doesn't correct that first, otherwise deleting <code>android/local.properties</code> achieves nothing.<syntaxhighlight lang="shell-session">FAILURE: Build failed with an exception. | |||

* There might be cases where setting the <code>ANDROID_HOME</code> environment variable will have no effect on Flutter's ability to assess the validity of Android SDK's installation. This behavior may be caused by an existing configuration file (<code>$XDG_CONFIG_HOME/settings</code> or <code>$XDG_CONFIG_HOME/flutter/settings</code>) containing an incorrectly set <code>"android-sdk"</code> key-value pair. Once removed, the environment variable should no longer be overridden, and should function correctly. | |||
