  Exception: SomeException

Implementation

static LoggerFormatter defaultFormatter =
    (LogContext context, LoggerDateFormatter? dateFormatter) {
      final buffer = IndentingStringBuffer();
      final now = context.timestamp;
      final timeString = dateFormatter != null
          ? dateFormatter(now)
          : defaultDateFormatter(now);
      buffer.writeRaw(timeString);
      buffer.writeRaw(' [${context.level.name}]');
      buffer.writeRaw(' [${context.scope}]');
      buffer.writeRaw(' ${context.message}');

      if (context.throwable != null || context.stackTrace != null) {
        buffer.newLine();
        buffer.indent();
        if (context.throwable != null) {
          if (context.throwable is Exception) {
            buffer.writeBlock(
              '\x1B[31mException: ${context.throwable}\x1B[0m',
            );
          } else {
            buffer.writeBlock('\x1B[31mError: ${context.throwable}\x1B[0m');
          }
        }
        if (context.stackTrace != null) {
          buffer.writeLine('StackTrace:');
          buffer.writeBlock(Trace.from(context.stackTrace!).terse.toString());
        }
        buffer.outdent();
      }
      return buffer.toString();
    };
