startScan static method

Future<ScanResult?> startScan({
  1. bool isContinuousClick = true,
  2. bool isToastDebug = false,
})

扫码 isContinuousClick 是否连续点击 true-是 isToastDebug 是否toast 用于测试 true-是

Implementation

static Future<ScanResult?> startScan({
  bool isContinuousClick = true,
  bool isToastDebug = false,
}) async {
  if (isContinuousClick) {
    if (isClick) return null;
    isClick = true;
    Future.delayed(Duration(milliseconds: 500), () => isClick = false);
  }
  if (isToastDebug) ToastUtils.showLong("调起原生扫码");
  Map<String, Object> map = {"isToast": isToastDebug};
  try {
    var result = await _channel.invokeMethod('startScan', map) as Map;
    final scanType = result['scanType'] as int;
    final scanTypeForm = result['scanTypeForm'] as int;
    final value = result['value'] != null ? result['value'] as String : null;
    final valueByte =
        result['valueByte'] != null ? result['valueByte'] as List<int> : null;
    print("========> scanType: $scanType");
    print("========> scanTypeForm: $scanTypeForm");
    print("========> value: $value");
    print("========> valueByte: $valueByte");
    ScanResult scanResult = ScanResult();
    scanResult.scanType = getScanType(scanType);
    scanResult.scanTypeForm = getScanTypeFormat(scanTypeForm);
    scanResult.value = value;
    scanResult.valueByte = valueByte;
    if (isToastDebug) ToastUtils.showLong("扫码成功：$value");
    return scanResult;
  } catch (e) {
    print(e);
    ToastUtils.showLong("调起扫码失败：$e");
    return null;
  }
}
