NoSuchMethodError: The method 'cast' was called on null.

[blue7wings]

hi, I can't generate asset, maybe cause by code error.

Dart SDK version: 2.9.0-21.10.beta (beta) (Tue Jul 21 10:46:30 2020 +0200) on "windows_x64"

I'm still seeing this issue.

[SEVERE]
NoSuchMethodError: The method 'cast' was called on null.
Receiver: null
Tried calling: cast<String>()

No files generated.

Can we please keep this open @wasabeef ? I know you've already fixed it but it might be useful for people to know that the package won't work until that version is released.

@lifenautjoe
Sorry I'm not yet releasing the fix version of 1.0.1.
Can I ask you? Which uses your PC? macos?ubuntu?windows?

[lifenautjoe]

Thanks @wasabeef :-)

I'm on MacOS.

Here's my Flutter doctor in case it helps.

[✓] Flutter (Channel unknown, 1.20.3, on macOS 11.0 20A5354i, locale en-NL)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.0)
[✓] Xcode - develop for iOS and macOS (Xcode 12.0)
[✓] Android Studio (version 4.0)
[✓] IntelliJ IDEA Ultimate Edition (version 2020.1.3)
[✓] VS Code (version 1.48.0)
[!] Connected device

I've also tried using the main branch which has the patch merged but still see the same error. I'm guessing you already know though if you're asking me for my device details :-)

[lifenautjoe]

Correction, the main branch does work. Sorry, caching issue.

@lifenautjoe

I will release v1.0.1 within an hour.
