Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The exif package enables decoding of Exif metadata from digital image files in formats including TIFF, JPEG, HEIC, PNG, and WebP. It provides a straightforward API to extract embedded information such as camera model, GPS coordinates, timestamps, and exposure settings. Designed for cross-platform use, it supports Android, iOS, macOS, Windows, and Linux. The package is ideal for applications requiring detailed image provenance or geotagging capabilities. Built on Dart, it integrates seamlessly with Flutter projects.

Use cases

  • Extracting camera details from photos
  • Retrieving GPS location data from images
  • Analyzing image capture timestamps
  • Validating image metadata integrity
  • Supporting photo management apps

Key features

  • Supports multiple image formats
  • Cross-platform compatibility
  • Simple API for metadata extraction
  • Lightweight and efficient
  • Open-source with active maintenance

  final data = await readExifFromBytes(fileBytes);

  if (data.isEmpty) {
    print("No EXIF information found");
    return;
  }

  if (data.containsKey('JPEGThumbnail')) {
    print('File has JPEG thumbnail');
    data.remove('JPEGThumbnail');
  }
  if (data.containsKey('TIFFThumbnail')) {
    print('File has TIFF thumbnail');
    data.remove('TIFFThumbnail');
  }

  for (final entry in data.entries) {
