isPDF static method

Future<bool> isPDF(
  1. String filePath
)

Determines whether the given file path corresponds to a PDF file.

This method uses the file's magic number (file signature) to accurately detect if the file is a PDF, regardless of its extension. This is more reliable than checking only the file extension.

Parameters:

  • filePath: The absolute path to the file to check

Returns: true if the file is a valid PDF, false otherwise (including when an error occurs during detection)

Implementation

static Future<bool> isPDF(String filePath) async {
  try {
    return await FileMagicNumber.detectFileTypeFromPathOrBlob(filePath) ==
        FileMagicNumberType.pdf;
  } catch (e) {
    return false;
  }
}
