包含path_provider时出错

Question

I get an error when I'm trying to compile path_provider:

/home/user/projects/flutterframework/TestApp/android/app/src/main/java/io/flutter/plugins/PluginRegistry.java:15:

error: cannot find symbol

path_provider = PathProviderPlugin.register(activity);

symbol: method register(FlutterActivity)

location: class PathProviderPlugin

1 error

FAILURE: Build failed with an exception.

What went wrong:

Execution failed for task ':app:compileDebugJavaWithJavac'.

Compilation failed; see the compiler error output for details.

How can I fix it? Lubuntu 16 LTS x64

It sounds like you have an old project template. You shouldn't have a PluginRegistry.java. Try flutter upgrade, recreate your project and copy the old project's dart files and assets over.
