windows - 在 Flutter for desktop (Windows) 中加载资产

Question

我正在尝试在 Flutter for Windows 中加载 SQLite DB（它在 Android 上运行），但我收到一个异常，我的代码是：

// Copy from asset
ByteData data = await rootBundle.load(join("assets", "mydb.sqlite"));
List<int> bytes = data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);

我收到此异常：

[错误：flutter/lib/ui/ui_dart_state.cc(199)] 未处理的异常：无法加载资产：assets\mydb.sqlite #0 PlatformAssetBundle.load (package:flutter/src/services/asset_bundle.dart:224:7 ) #1 DatabaseHelper._initDatabase (package:myapp/database_helper.dart:54:11) #2 DatabaseHelper.database (package:myapp/database_helper.dart:29:17) #3 DatabaseHelper.queryAllRows (package:myapp/database_helper.dart :80:19) #4 _MyHomePageState._query (package:myapp/main.dart:193:15)
