A command-line application to highlight dart source code.
Code segments are highlighted before the app is compiled. This is done because the highlighting process can take 300ms to finish, creating a noticeable delay when the demo switches to code page.
The highlighter takes all files in the
gallery/lib/demos/ folder and scans each. Highlighted code widgets are stored in the
flutter pub get.
flutter pub run grinder update-code-segmentsto generate code segments with highlighting.
Wrap a block of code with lines
// BEGIN yourDemoName and
// END to mark it for highlighting. The block in between, as well as any copyright notice and imports at the beginning of the file, are automatically taken and highlighted, and stored as
static TextSpan yourDemoName(BuildContext context) in
gallery/lib/codeviewer/code_segments.dart. To display the code, go to
gallery/lib/data/demos.dart, and add
code: CodeSegments.yourDemoName, to your
Use the following method to join multiple blocks of code into a single segment:
// BEGIN yourDemo#2 a(); // END b(); // BEGIN yourDemo#1 c(); // END
The generated code will be
Code blocks can nest or overlap. In these cases, specify which file(s) to
The following source file
// BEGIN demoOne a(); // BEGIN demoTwo b(); // END demoOne c(); // END demoTwo
will create the following segments: (demoOne)
