Flutter3.0
What did you do?
Now, I'm using version Flutter 3.0. But, this SDK using Dart SDK version 2.16.2
What did you expect?
Please version up.
What happened actually?
flutter pub add flutter_line_sdk
The current Dart SDK version is 2.16.2.
Because PACKAGE_NAME requires SDK version >=2.17.0 <3.0.0, version solving failed.
That is not a thing of Flutter version, but a requirement of Dart SDK version.
LINE SDK flutter requires from Dart SDK 2.12.0 (see here) and your current version 2.16.2 is totally legal for this.
The reported issue
Because PACKAGE_NAME requires SDK version >=2.17.0 <3.0.0, version solving failed.
indicates the PACKAGE_NAME requires Dart SDK 2.17.0, which I guess is not a requirement from LINE SDK flutter. I would suggest you check to see how can you solve it by contacting the maintainer of PACKAGE_NAME or just upgrading your Dar SDK version (maybe by flutter upgrade).
There is no additional information and since this package can work seamlessly with Flutter 3.0, I am closing this issue for now.
Feel free to reopen the discussion if there is any new information appended. Thanks!
