File - Type Checks

Powerful extensions for dart:io.File to simplify size formatting, path manipulation, and type checking for local files.

1. Getters

   type · FileType

   Resolves and returns the general FileType based on a hierarchical check of the file’s extension and name.

   final type = File('song.mp3').type; // FileType.audio
   
   switch (type) {
       case FileType.image: ...
       case FileType.unknown: ...
   }
   

   isImage · bool

   Checks if the file is likely a raster image based on its extension.

   Supports common formats: jpg, jpeg, png, gif, bmp, webp.

   print(File('profile.JPG').isImage); // true
   

   isAudio · bool

   Checks if the file is likely an audio file.

   Supports common formats: mp3, wav, aac, flac, m4a, ogg, wma.

   print(File('music.mp2').isAudio); // true
   

   isVideo · bool

   Checks if the file is likely a video file.

   Supports common formats: mp4, mkv, mov, avi, webm, wmv.

   print(File('clip.mp4').isVideo); // true
   

   isDocument · bool

   Checks if the file is a general-purpose document, covering text, office, and PDF formats.

   This is a broad check, combining the extensions from isTextDocument, isSpreadsheet, and isPresentation.

   print(File('docs.xlsx').isDocument); // true
   

   isPresentation · bool

   Checks if the file is a presentation file format.

   Supports common formats: ppt, pptx, key, odp.

   Supports common formats: xls, xlsx, csv, ods and more.

   print(File('docs.csv').isSpreadsheet); // true
   

   isTextDocument · bool

   Checks if the file is a general text or readable document file (PDF, Word, Markdown, etc.).

   Supports common formats: pdf, doc, docx, txt and more.

   print(File('sampleTextFile.txt').isTextDocument); // true
   

   isExecutable · bool

   Checks if the file is likely an executable or system binary file.

   Supports common formats: exe, apk, aab, dmg, bat, sh, bin, iso, msi.

   print(File('ExeFile.exe').isExecutable); // true
