方法重载Overload for FirmwareManager.statSync and FirmwareManager.statSync

[bradleyzhou]

Problem 问题

从3.3.2升级至3.4.2时，代码中statSync部分报错，如： When we upgrade from 3.3.2 to 3.4.2, code related to statSync throws error while build,

const fs = wx.getFileSystemManager();
const stat = fs.statSync('filePath');
return stat.isFile();
//          ~~~~~~
// Error: Property 'isFile' does not exist on type 'Stats[]'.

Suggestions 建议

提供重载，方便已有代码推断正确类型。 Can you provide Overrides for automatic Type inference?

Examples FYI 示意

• statSync

  interface FileSystemManager {
    statSync(
      path: string,
      recursive?: false
    ): Stats;
    statSync(
      path: string,
      recursive: true
    ): Stats[];
  }
  

• stat

    interface FileSystemManager {
        stat(option: NonRecursiveStatOption): void
        stat(option: RecursiveStatOption): void
    }
  
    interface NonRecursiveStatOption {
        path: string
        complete?: StatCompleteCallback
        fail?: StatFailCallback
        recursive?: false
        success?: NonRecursiveStatSuccessCallback
    }
    interface RecursiveStatOption {
        path: string
        complete?: StatCompleteCallback
        fail?: StatFailCallback
        recursive: true
        success?: RecursiveStatSuccessCallback
    }
    interface NonRecursiveStatSuccessCallback {
        stats: Stats
        errMsg: string
    }
    interface RecursiveStatSuccessCallback {
        stats: Stats[]
        errMsg: string
    }
