[BUG]: .svg.vec Metadata Parsing Issue with Repeated Build

[koutja]

Is there an existing issue for this?

• [x] I have searched the existing issues

Version

5.10.0

Command type

build_runner (Default)

What happened?

When running the build command with settings that include .svg.vec files (generated by vector_graphics_compiler), the file is generated correctly the first time. However, running the build command again does not update the file as expected. The following warning consistently appears in the console:

[WARNING] Failed to parse SVG 'assets/vec/markers/disabled.svg.vec' metadata: FileSystemException: Failed to decode data using encoding 'utf-8'

Configuration

flutter_gen:
  parse_metadata: true

Expected Result

• On every build, .svg.vec files should be correctly updated if their sources have changed.
• No warnings about metadata parsing or encoding errors should appear.

Actual Result

• The file is generated correctly only on the first build.
• On subsequent builds, the file is not updated.
• The warning about failing to parse SVG metadata due to a UTF-8 decoding error appears every time.

Steps to Reproduce

• Generate .svg.vec files using vector_graphics_compiler.
• Configure flutter_gen with parse_metadata: true.
• Run the build command.
• Observe that the file is created correctly.
• Run the build command again without changing the source.
• Observe that the file is not updated and the warning appears.

Relevant a pubspec.yaml.
