添加图像到flutter分支sdk包

Question

是否有办法从目录路径或从资产文件夹添加图像到分支sdk flutter包生成的链接，而不是网络图像链接?

buo = BranchUniversalObject(
canonicalIdentifier: 'flutter/branch',
//parameter canonicalUrl
//If your content lives both on the web and in the app, make sure you set its canonical URL
// (i.e. the URL of this piece of content on the web) when building any BUO.
// By doing so, we’ll attribute clicks on the links that you generate back to their original web page,
// even if the user goes to the app instead of your website! This will help your SEO efforts.
canonicalUrl: 'https://flutter.dev',
title: 'Flutter Branch Plugin',
imageUrl:
'https://flutter.dev/assets/flutter-lockup-4cb0ee072ab312e59784d9fbf4fb7ad42688a7fdaea1270ccf6bbf4f34b7e03f.svg',

..addCustomMetadata('custom_bool', true)

..addCustomMetadata('custom_list_string', ['a', 'b', 'c']),
