The following error occurred while importing the plugin：
Because cr_logger >=2.4.2 depends on package_info_plus ^5.0.1 and fou depends on package_info_plus ^8.0.2, cr_logger >=2.4.2 is forbidden.
So, because fou depends on cr_logger ^2.4.2, version solving failed.
ecause shared_preferences_web >=2.4.1 depends on web >=0.5.1 <2.0.0 and shared_preferences_web >=2.3.0 <2.4.1 depends on web ^0.5.0, shared_preferences_web >=2.3.0 requires web >=0.5.0 <2.0.0.

Please specify a range when configuring package dependencies, instead of directly writing down a certain version
for example：
dependencies:
url_launcher: '<=0.2.0'
url_launcher: '>0.1.2 <0.2.0'
url_launcher: '>=0.1.2'
