在Flutter中设置蓝牙设备名称

Question

在Android中使用BluetoothAdapter.getDefaultAdapter().setName()可以更改蓝牙设备名称，但我找不到如何在Flutter中更改。我试过使用flutter_blue软件包；然而，我不知道我们如何才能做到这一点。

提前感谢！

// BT Rename
//
final String sNewName = "Syntactics";
final BluetoothAdapter myBTAdapter = BluetoothAdapter.getDefaultAdapter();
final long lTimeToGiveUp_ms = System.currentTimeMillis() + 10000;
if (myBTAdapter != null)
{
String sOldName = myBTAdapter.getName();
if (sOldName.equalsIgnoreCase(sNewName) == false)
{
final Handler myTimerHandler = new Handler();
myBTAdapter.enable();
myTimerHandler.postDelayed(
new Runnable()
{
@Override
public void run()
{
if (myBTAdapter.isEnabled())
{
myBTAdapter.setName(sNewName);
if (sNewName.equalsIgnoreCase(myBTAdapter.getName()))
{
Log.i(TAG_MODULE, "Updated BT Name to " + myBTAdapter.getName());
myBTAdapter.disable();
}
}
if ((sNewName.equalsIgnoreCase(myBTAdapter.getName()) == false) && (System.currentTimeMillis() < lTimeToGiveUp_ms))
{
myTimerHandler.postDelayed(this, 500);
if (myBTAdapter.isEnabled())
Log.i(TAG_MODULE, "Update BT Name: waiting on BT Enable");
else
Log.i(TAG_MODULE, "Update BT Name: waiting for Name (" + sNewName + ") to set in");
}
}
} , 500);
}
}
