run method

@override Future<int> run(Iterable<String> args)

Parses args and invokes Command.run on the chosen command.

This always returns a Future in case the command is asynchronous. The Future will throw a UsageException if args was invalid.

Implementation

@override
Future<int> run(Iterable<String> args) async {
  try {
    final ArgResults argResults = parse(args);
    final int exitCode =
        await runCommand(argResults) ?? ExitCode.success.code;
    return exitCode;
  } on SvgToFlutterException catch (e) {
    stderr.writeln('\x1b[31m ❌ $e ❌');
    return ExitCode.usage.code;
  } on SvgToFlutterUsageException catch (e) {
    stderr.writeln('\x1b[31m ❌ $e ❌');
    return ExitCode.usage.code;
  } on UsageException catch (e) {
    stderr.writeln('\x1b[31m ❌ $e ❌');
    return ExitCode.usage.code;
  } on Exception catch (e) {
    stderr.writeln('\x1b[31m ❌ $e ❌');
    return ExitCode.usage.code;
  }
}
