InfoView class

A read-only panel showing document metadata and file information.

InfoView renders two sections:

1. Document metadata — PdfMetadata fields (title, author, subject, keywords, creator, producer, creation date, modification date).
2. File information — optional file name, file path, file size, page count, PDF version, and filesystem dates.

File info is passed as parameters rather than fetched internally, keeping the widget free of dart:io and making it straightforward to test.

All string fields are rendered as labelled rows with the label in a muted style and the value in primary text. Missing or null fields are omitted entirely. Dates are formatted via intl.DateFormat using pdfDate.value (a DateTime? in UTC); the raw string is never shown.

File size is formatted as a human-readable string (e.g. "1.2 MB") using NumberFormat.decimalPattern.

Example

InfoView(
  metadata: meta,
  docInfo: info,
  pageCount: 42,
  filePath: '/path/to/document.pdf',
  fileSizeBytes: 1234567,
  labels: PdfDocumentInfoLabels(...),
)
