+With Sentry Structured Logs, you can send text based log information from your applications to Sentry. Once in Sentry, these logs can be viewed alongside relevant errors, searched by text-string, or searched using their individual attributes.

+
+To filter logs, or update them before they are sent to Sentry, you can use the `beforeSendLog` option.
+
+```dart
+await SentryFlutter.init(
+  (options) {
+    options.dsn = "___PUBLIC_DSN___";
+    options.beforeSendLog = (log) {
+      if (log.level == SentryLogLevel.info) {
+        // Filter out all info logs
+        return null;
+      }
+
+      return log;
+    };
+  },
+);
+```
+
+The `beforeSend` function receives a log object, and should return the log object if you want it to be sent to Sentry, or `null` if you want to discard it.

+Once the feature is enabled on the SDK and the SDK is initialized, you can send logs using the `Sentry.logger` APIs.
+
+The `logger` namespace exposes six methods that you can use to log messages at different log levels: `trace`, `debug`, `info`, `warning`, `error`, and `fatal`.
+
+You can pass additional attributes directly to the logging functions. These properties will be sent to Sentry, and can be searched from within the Logs UI, and even added to the Logs views as a dedicated column.
+
+```dart
+Sentry.logger.info("A simple log message");
+Sentry.logger.warn("This is a warning log with attributes.", attributes: {
+  'string-attribute': SentryLogAttribute.string('string'),
+  'int-attribute': SentryLogAttribute.int(1),
+  'double-attribute': SentryLogAttribute.double(1.0),
+  'bool-attribute': SentryLogAttribute.bool(true),
+});
