Flutter Obj-C plug-in how to get an argument?

Question

This is what I'm using:

- (void)handleMethodCall:(FlutterMethodCall*)call result:(FlutterResult)result {
  if ([@"loadImage" isEqualToString:call.method]) {
    NSData* data = UIImageJPEGRepresentation(call.arguments[@"filePath"], 0.8);
    result(@"success");
  } else {
    result(FlutterMethodNotImplemented);
  }

However, I'm not sure if it's call.arguments , that's what it is on Java.

How can I go about getting auto-completion for plugin writing?

Answer 1

是的， call.arguments是一个NSDictionary （参见Java HashMap ），因此您可以使用以下命令提取String参数：

NSString *value = call.arguments[@"argName"];
