excel_plus 0.0.4

Read, create, and edit Excel .xlsx files in Dart and Flutter with high performance and low memory usage.

0.0.4

• Upgraded the xml dependency to ^7.0.1 and updated internal XML name handling for compatibility.
• Reworked the example app into a real workbook demo with import, inline editing, styling, sheet tools, and export flows.
• Added a dedicated Validation Lab screen, bundled workbook sample, and safer temp-directory fallback when platform storage plugins are unavailable.
• Improved the example web bootstrap so debug runs use a compatible renderer while wasm builds still opt into skwasm.

0.0.3

• Organized API docs into 5 categories: Core, Cell Values, Styling, Number Formats, Layout.
• Hidden internal APIs (Parser, ExcelWriter, FastList, etc.) from public documentation.
• Improved dartdoc comments across all public classes and methods.
• Cleaned up Excel class method docs with proper one-line summaries.

0.0.2

• Removed collection and equatable dependencies — reduced to 3 deps (archive, xml, web).
• Codebase cleanup: removed dead code, duplicate utilities, and redundant comments.
• Consolidated XML escaping into a single shared utility.
• Extracted common date/time fraction calculation helper.
• Fixed minimum xml constraint to ^6.3.0 for downgrade compatibility.

0.0.1

• Initial release.
• Performance-optimized fork of excel v5.0.0.
• SAX-based streaming parser replaces full DOM parsing for cell data and shared strings.
• Lazy sheet loading — sheets are parsed on first access, not at file open.
• O(1) cell style lookup via cached reverse index.
• Smart archive cloning — reuses unmodified ZIP entries instead of copying.
• Fixed-point span correction algorithm with early termination.
• 100% API compatible — drop-in replacement for the excel package.
• 76 unit tests + 13 integration tests on Android emulator.
