Source lines of Code

Source lines of Code is an approximate number of source code lines in a function or method. Blank or comment lines are not counted.

This metric is used to measure the size of a computer program by counting the number of lines in the text of the program's source code. SLOC is typically used to predict the amount of effort that will be required to develop a program, as well as to estimate programming productivity or maintainability once the software is produced.

Config example

source-lines-of-code: 50


MetricComputationResult<int> computeImplementation(
Declaration node,
Iterable<ScopedClassDeclaration> classDeclarations,
Iterable<ScopedFunctionDeclaration> functionDeclarations,
InternalResolvedUnitResult source,
) {
final visitor = SourceCodeVisitor(source.lineInfo);

return MetricComputationResult(
value: visitor.linesWithCode.length,
context: _context(node, visitor.linesWithCode, source),

Source lines of Code for the example function is 6.
