问题描述
当前 Dart SDK 版本为 2.12.2。
Because audioplayers 0.18.3 depends on uuid ^3.0.1 which depends on crypto ^3.0.0,audioplayers 0.18.3 requires crypto ^3.0.0.
(1) 因此，因为存档 >=2.0.0 =2.0.0
Because image >=2.0.4 <2.1.14 depends on archive >=1.0.16 <3.0.0 and archive ^1.0.2 requires SDK version <2.0.0,image >=2.0.4 <2.1.14 requires archive ^2.0.0.
And because Flutter_launcher_icons >=0.7.1 <0.9.0 depends on image ^2.1.1 and image >=2.1.14 <3.0.0-nullsafety.0 depends on archive ^2.0.0,Flutter_launcher_icons >=0.7.1 <0.9.0 requires archive ^2.0.0.
And because audioplayers 0.18.3 is incompatible with archive >=2.0.0 <3.0.0-nullsafety.0 (1),audioplayers 0.18.3 is incompatible with Flutter_launcher_icons >=0.7.1 <0.9.0.
So,because touch_sensitive_alarm depends on both Flutter_launcher_icons ^0.7.2+1 and audioplayers 0.18.3,version solving Failed.
pub get Failed (1; 所以，因为 touch_sensitive_alarm 依赖于 Flutter_launcher_icons ^0.7.2+1 和 audioplayers 0.18.3，版本解析失败。)
解决方法
因为您使用当前的 Dart SDK，所以您必须检查所有包是否有 null-safety 并在更新时更新该包。
希望能帮到你
