Clipboard

Clipboard data is represented by a ClipboardContent record containing a MIME type and its raw bytes. The API returns FutureOr values, so it can be used consistently with await on every platform.

import 'dart:convert';
import 'dart:typed_data';

import 'package:lw_sysapi/lw_sysapi.dart';

Future<String?> copyAndReadText() async {
  final clipboard = await SysAPI.getClipboardManager();

  final copied = await clipboard.setContent((
    type: ClipboardMimeTypes.text,
    data: Uint8List.fromList(utf8.encode('Hello from lw_sysapi')),
  ));
  if (!copied) return null;

  final content = await clipboard.getContent(
    types: const [ClipboardMimeTypes.text],
  );
  if (content == null) return null;

  return utf8.decode(content.data);
}

Pass MIME types to getContent in preference order. When types is omitted, the manager checks the types in ClipboardMimeTypes.defaultTypes.

Binary data uses the same API:

Future<bool> copyPng(Uint8List pngBytes) async {
  final clipboard = await SysAPI.getClipboardManager();
  return clipboard.setContent((
    type: ClipboardMimeTypes.png,
    data: pngBytes,
  ));
}

getContent returns null and setContent returns false when the requested operation is unavailable or unsupported. Use SysAPI.getClipboardManager(internal: true) for an in-memory, process-local clipboard instead of the system clipboard.
