Hello.
I have this trouble.
Do you have any solution?

If I will do it then I post it here.

Hello guys,
I do have the same problem. It would be great if someone could post a solution.

What version of sqflite are you using? I recommend using the latest version (sqflite: '>=0.8.4' in pubspec.yaml)

[alextekartik]

Indeed there seems to be an issue with the latest dev version (cast method has been removed from List/Map). I'll take a look tomorrow....

[alextekartik]

I was not able to reproduce using the lastest flutter dev/beta version and I update the package with deprecation warning fix (0.8.5). Can you try again (and check my troubleshoot section here: https://github.com/tekartik/sqflite/blob/master/doc/troubleshooting.md)

Okay, I found my mistake:

I forgot the <String, dynamic> at the toMap() method (Map<String, dynamic> toMap())

[alextekartik]

yes indeed. That's definitely a must for dart 2; I had many crashes with that have required some fixes in the library itself (that's why I recommend the implicit-casts: false which sounds noisy at first but helps catching such issues. Good that you found it!

I added a note in the troubleshooting section on this specific common issue: https://github.com/tekartik/sqflite/blob/master/doc/troubleshooting.md#cast-error
