readExifFromFile function

Future<Map<String, IfdTag>> readExifFromFile(File file, { String? stopTag, bool details = true, bool strict = false, bool debug = false, bool truncateTags = true, })

Reads EXIF metadata from a File object asynchronously.

This is a streaming version of readExifFromBytes.

file: The image file to extract EXIF data from. stopTag: Optional tag name to stop parsing at. details: Whether to include detailed information (default: true). strict: Whether to use strict parsing (default: false). debug: Whether to enable debug output (default: false). truncateTags: Whether to truncate long tag values (default: true).

Returns a map of tag names to IfdTag objects.

Implementation

Future<Map<String, IfdTag>> readExifFromFile(
  File file, {
  String? stopTag,
  bool details = true,
  bool strict = false,
  bool debug = false,
  bool truncateTags = true,
}) async {
  final randomAccessFile = await file.open();
  try {
    final fileReader = await FileReader.fromFile(randomAccessFile);
    final r = await readExifFromFileReaderAsync(
      fileReader,
      stopTag: stopTag,
      details: details,
      strict: strict,
      debug: debug,
      truncateTags: truncateTags,
    );
    return r.tags;
  } finally {
    await randomAccessFile.close();
  }
