DefaultLogSink

A LogSink that writes to each platform's native log output:

• Android - android.util.Log (visible in Logcat)

• iOS / macOS - NSLog (visible in the Xcode console)

• JS / Wasm - the browser or Node.js console

• JVM / Linux / Windows - standard output

This is the sink installed automatically when LoggerFactory.install is never called, and the recommended one during development: every level appears where developers already look.

The output format is controlled by logFormatter. Defaults to LogFormatters.pretty without emoji.

A throwable is rendered once, by the platform channel itself (on JS as the error object), so logFormatter receives the event without it. As a result LogFormatters.json output from this sink has no error field; use ConsoleSink or RemoteLogSink for pure JSON lines.

Example:

LoggerFactory.install(
    LoggerConfig.Builder()
        .addSink(DefaultLogSink())
        // or with a custom formatter
        .addSink(DefaultLogSink(LogFormatters.compact(showEmoji = true)))
        .build()
)
