impl Channel for StandardMethodChannel

type Codec = StandardMethodCodec

type R = Value

fn get_name(&self) -> &str

fn init(&self, registry: *const PluginRegistry)

fn get_engine(&self) -> Option<Weak<FlutterEngineInner>>

fn invoke_method(&self, method_call: MethodCall<Self::R>)

Invoke a flutter method using this channel

fn decode_method_call(&self, msg: &PlatformMessage) -> MethodCall<Self::R>

Decode dart method call

fn send_success_event(&self, data: &Self::R)

When flutter listen to a stream of events using EventChannel. This method send back a success event. It can be call multiple times to simulate stream.

fn send_error_event(&self, code: &str, message: &str, data: &Self::R)

When flutter listen to a stream of events using EventChannel. This method send back a error event. It can be call multiple times to simulate stream.

fn send_method_call_response(
    &self,
    response_handle: Option<&FlutterPlatformMessageResponseHandle>,
    ret: MethodCallResult<Self::R>
) -> bool

Send a method call response

fn send_response(
    &self,
    response_handle: &FlutterPlatformMessageResponseHandle,
    buf: &[u8]
)

When flutter call a method using MethodChannel, it can wait for rust response using await syntax. This method send a response to flutter. This is a low level method. Please use send_method_call_response if that will work.

fn send_platform_message(&self, msg: &PlatformMessage)

Send a platform message over this channel. This is a low level method.
