- Transitioned to the new Gradle plugin and updated Gradle wrapper to version 8.7. - Refactored build.gradle files to use the new plugins DSL and updated Kotlin version. - Updated AndroidManifest.xml to remove the package attribute and ensure proper permissions. - Enhanced MediaScanner.kt and AudioMediaScannerExtractor.kt for better handling of artist names and added support for additional media attributes. - Updated pubspec.yaml to reflect new SDK constraints and dependency versions.
- Updated title extraction logic to use ifBlank for better readability. - Fixed album cover retrieval by using the correct album ID. - Enhanced createCover method to save album covers in a dedicated directory and handle image compression to WEBP format. - Improved error handling during cover creation process.
WalkthroughThis pull request modernizes the mediascanner Flutter plugin's Android build infrastructure and enhances media extraction capabilities. Updates include migrating from legacy Groovy Gradle DSL to modern plugins DSL, upgrading Gradle from 7.2 to 8.7, increasing Android compilation SDK to 35 with Java 17 support, refining Kotlin dependencies, improving ID3 tag handling in media extraction, enhancing album cover generation, and updating Flutter/Dart dependencies for null safety.

9-12: Top-levelrepositoriesblock may be redundant.With plugin resolution handled in
settings.gradleviapluginManagement, you can also add adependencyResolutionManagementblock insettings.gradlefor dependency repositories. This centralizes repository configuration and avoids the need for per-module repository declarations.However, this is not blocking since the current setup works.

- Around line 218-221: The cache lookup uses albumCache[albumId] != null which
treats a cached null (negative lookup) the same as a missing key; change the
check to albumCache.containsKey(albumId) so that a stored null value is honored
and the function returns albumCache[albumId] without re-querying the DB; update
the branch that currently returns when albumCache[albumId] != null to use
albumCache.containsKey(albumId) and keep the existing behavior of returning
albumCache[albumId] when the key exists.
- Around line 152-153: The code calls id3v2Tag.albumArtist.isNotEmpty() which
can be null at runtime; guard the albumArtist platform-type for null before
calling isNotEmpty() — e.g., check id3v2Tag.albumArtist != null &&
id3v2Tag.albumArtist.isNotEmpty() or use a null-safe check like
!id3v2Tag.albumArtist.isNullOrEmpty() and then assign artist =
id3v2Tag.albumArtist when that check passes (preserving the existing logic
comparing to UNKNOWN_ARTIST).
In `@packages/mediascanner/example/pubspec.yaml`:
- Line 9: Update the Dart SDK lower bound in pubspec.yaml to satisfy the
upgraded dependency by changing the sdk constraint from ">=2.12.0 <4.0.0" to a
constraint that includes Dart 3.5 (e.g., ">=3.5.0 <4.0.0"); ensure this aligns
with the permission_handler: ^12.0.1 dependency declared in the dependencies
section so the package resolver no longer fails due to an unsupported SDK lower
bound.

mp3agic ID3v2Tag albumArtist null nullable return type
💡 Result:
In mp3agic, ID3v2#getAlbumArtist() is declared to return a String (not a primitive / not Optional). It is not annotated as @Nullable in the public API. [1]
In practice, mp3agic tag getters commonly return null when the corresponding ID3v2 frame is missing (so you should treat the result as nullable). The concrete implementation is AbstractID3v2Tag#getAlbumArtist(), with signature public String getAlbumArtist(). [2] This “nullable when absent” behavior is also seen with other mp3agic getters (e.g., getLyrics() returning null when not present). [3]
So:
- Java: return type is
String, but you should null-check it. - Kotlin: model it as
String?.

Guard albumArtist nullability before calling isNotEmpty().
Line 152 can throw NullPointerException at runtime. Although ID3v2#getAlbumArtist() declares a non-nullable return type in mp3agic, the implementation returns null when the corresponding ID3v2 frame is missing. In Kotlin, this is treated as a platform type (String!), and calling .isNotEmpty() without null-checking will crash if the frame is absent.

- artist = id3v2Tag.albumArtist

Use containsKey() to properly cache negative lookups.
The albumCache intentionally stores null values for not-found albums (lines 215, 251), but the check albumCache[albumId] != null cannot distinguish between "key not in cache" and "key cached with null value". This causes the database query at line 225 to repeat for the same albumId even when a negative lookup was already cached. Replace with containsKey(albumId):
Proposed fix
- if (albumCache[albumId] != null) {
+ if (albumCache.containsKey(albumId)) {
// Timber.d("Album $albumId is present in cache")
return albumCache[albumId]
