2.Flutter

2.1去除水波纹，增加滚动条

ScrollConfiguration(
    behavior: ScrollBehavior(),
    child: CupertinoScrollbar(
      child: SingleChildScrollView(
        child: Container()
      ）
    ）
）

2.2Flutter运行项目报错Build failed due to use of deprecated Android v1 embedding.

1.找到AndroidManifest.xml
2.删除name属性
  android:name="io.flutter.app.FlutterApplication"
3.在activity标签下添加
  <meta-data android:name="flutterEmbedding" android:value="2"/>

2.3.flutter_blue插件调用characteristic.read方法报错

Exception has occurred.
PlatformException (PlatformException(read_characteristic_error, unknown reason, may occur if readCharacteristic was called before last read finished., null))

在read之前判断有没有read权限

if(characteristic.properties.read){
   c.read();   
}

使用listen监听

await characteristic.setNotifyValue(true);
characteristic.value.listen((event) {
   // do
});
