[Flutter get_cli] 配置 sub_folder:false报错

flutter get_cli 配置

get_cli:
	sub_folder:false

报错如下
Because getx_cli_learn01 depends on get_cli from unknown source "sub_folder", version solving failed.

原因是在 pubspec.yaml文件中,

get_cli:
	sub_folder:false

要和

dependencies: 
	xxx
dev_dependencies: 
	xxx

同级

can create page without child folder? #113

sub_folder:true

sub_folder:false
