Flutter example for the gcode_core package.

It demonstrates the full local workflow:

• Pick a local .gcode, .nc, .tap, or .txt file.
• Read the file line by line with FileGcodeLineReader.
• Parse supported G0/G1 commands with GcodeReadlinePipeline.
• Dynamically refresh parsed snapshots while reading.
• Draw toolpath segments with the package-provided GcodeCanvas.
• Show G0 jump moves as red dashed lines and G1 cutting moves as solid paths.
• Show commands and parse errors with CommandTimeline.
• Preview the generated path with PlaybackControls.

The main integration points are:

final pipeline = GcodeReadlinePipeline(
  options: const GcodeReadlineOptions(snapshotBatchSize: 1),
);

await for (final snapshot in pipeline.load(FileGcodeLineReader(file.path))) {
  setState(() => _snapshot = snapshot);
}

GcodeCanvas(
  segments: snapshot.segments,
  progress: playbackProgress,
  errorCount: snapshot.errors.length,
);

Run it from this directory:

flutter run
