 # flutter-img-path

-一个Flutter 图片路径创建插件
+一个Flutter 图片路径创建插件
+
+灵感源自于https://github.com/Leo0618/flutter-img-sync
+
+ step1.创建图片存放目录 如: ./assets/home/img
+
+ step2.修改pubspec.yaml</b><br>
+  ```yaml
+    assets:
+      assets:
+      # assets-generator-begin
+      # lib/assets/home/img/*
+      # assets-generator-end
+  ```
+ step3.Tools--Flutter Img Path
+
+  pubspec.yaml中的assets变量会被配置项目的图片，并在./lib目录下生产r.dart文件
+  > 如果没效果。可以Ctrl + S 保存一下，或者关闭文件再打开 
+
+ step4.代码中导入r.dart文件，然后引用R类的变量
+
+快捷键：Alt + I
