Running "flutter pub get" in project_name...
The current Dart SDK version is 2.16.2.
Because no versions of qr_flutter match >4.0.0 and qr_flutter <1.1.2 requires SDK version >=1.8.0 <2.0.0, qr_flutter <1.1.2-∞ or >4.0.0 is forbidden.
And because qr_flutter >=1.1.2 <2.1.0+55 depends on qr ^1.0.0, qr_flutter <2.1.0+55 or >4.0.0 requires qr ^1.0.0.
And because qr_flutter ^2.1.0+55 depends on qr ^1.1.0 and qr_flutter ^3.0.0 depends on qr ^1.2.0, qr_flutter <4.0.0-∞ or >4.0.0 requires qr ^1.0.0.
And because qr_flutter 4.0.0 depends on qr ^2.0.0 and barcode >=2.2.0 depends on qr ^3.0.0, qr_flutter is incompatible with barcode >=2.2.0.
And because printing >=5.7.3 depends on pdf ^3.7.2 which depends on barcode ^2.2.0, qr_flutter is incompatible with printing >=5.7.3.
So, because sflo_zaiko depends on both qr_flutter any and printing ^5.8.0, version solving failed.
pub get failed (1; So, because project_name depends on both qr_flutter any and printing ^5.8.0, version solving failed.)
exit code 1
我做了“flutter 升级”，更改了这些依赖项的版本等。
(将 printing: ^5.8.0 更改为 printing: any 有效。但它确实会导致另一个错误，因此打印必须是版本 5.8.0)
最佳答案
请在 pubspec.yaml 中添加以下行。
dependency_overrides:
barcode: ^2.2.0
qr: ^3.0.1
关于Flutter pub 由于版本不匹配而失败。 (qr_flutter 和打印)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/72167002/
