Unhandled exception when running without releaseUrl

[RustamG]

I'm getting an error when release URL is not specified (neither in pubspec nor via env SQUIRREL_RELEASE_URL). Here is an example of pubspec.yaml section of

#.....
squirrel:
  windows:
    appFriendlyName: "Test App"
    appDescription: "Test App main application."
    appIcon: "windows/runner/resources/app_icon.ico"
    releaseDirectory: "ReleaseDir"

Error

Unhandled exception:
Exception: Failed to run c:\users\rustamg\appdata\local\pub\cache\hosted\pub.dartlang.org\squirrel-0.1.0\vendor\SyncReleases.exe -r c:\users\rustamg\test\test_squirrel\ReleaseDir -u c:\use

The issue seems to be here: https://github.com/anaisbetts/squirrel-flutter/blob/2979ed912f28b4b8b273db4ac19779868a9a9b2e/bin/installer_windows.dart#L163-L165

? should be placed before .toString(). Otherwise null becomes a string with a value "null".

@anaisbetts, Please, have a look

Hi @anaisbetts! Any chance a new version gets published soon?

@RustamG It's on my to-do list to finish this package, it's currently broken altogether with the latest Flutter because they create Snapshots of pub run tools which breaks some of the code here.
