KMP Serialization

Serialization

Use custom adapters when the public generated API should expose a domain type instead of the raw SQLite storage type.

CREATE TABLE task
(
    id INTEGER PRIMARY KEY NOT NULL,

    -- @@{ field=tags, adapter=custom, propertyType=List<String> }
    tags TEXT NOT NULL
);

val db = AppDatabase(
    dbName = dbPath,
    migration = VersionBasedDatabaseMigrations(),
    taskAdapters = AppDatabase.TaskAdapters(
        sqlColumnToTags = { value -> value.jsonDecodeFromSqlite() },
        tagsToSqlColumn = { tags -> tags.jsonEncodeToSqlite() },
    ),
)

Prefer stable serialized values for enums and timestamps. For absolute time, store RFC3339 text with an explicit zone instead of locale-specific strings.
