run method
Runs this tool and returns (either synchronously or asynchronously) an int which will be treated as the exit code (i.e. non-zero means failure).
context
is optional. If calling this directly from a dart script, you
will most likely want to omit this. DevTools that are converted to a
DevToolCommand via toCommand for use in a command-line application
will provide a fully-populated DevToolExecutionContext here.
This is the one API member that subclasses need to implement.
Implementation
@override
FutureOr<int?> run([DevToolExecutionContext? context]) async {
context ??= DevToolExecutionContext();
int? code = 0;
for (var i = 0; i < _specs.length; i++) {
if (!shouldRunTool(_specs[i].when, code)) continue;
final newCode =
await _specs[i].tool.run(contextForTool(context, _specs[i]));
_log.fine('Step ${i + 1}/${_specs.length} done (code: $newCode)\n');
if (code == 0) {
code = newCode;
}
}
return code;
