颤振酒吧会因版本错配而失败。(qr_flutter和印刷)

Question

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‘颤振升级’，更改了这些依赖项的版本等等。

(将printing: ^5.8.0改为printing: any有效。但是它确实会导致另一个错误，所以打印必须是5.8.0版)

Answer 1

请在pubspec.yaml中添加以下行。

dependency_overrides:
  barcode: ^2.2.0
  qr: ^3.0.1

Answer 2

删除颤振包中的版本代码
