Properties

hashCode → int

The hash code for this object.

no setter, inherited

mavlinkCrcExtra → int

no setter, override

mavlinkMessageId → int

no setter, override

messageType → uint16_t

A code that identifies the software component that understands this message (analogous to USB device classes or mime type strings). If this code is less than 32768, it is considered a 'registered' protocol extension and the corresponding entry should be added to https://github.com/mavlink/mavlink/definition_files/extension_message_ids.xml. Software creators can register blocks of message IDs as needed (useful for GCS specific metadata, etc...). Message_types greater than 32767 are considered local experiments and should not be checked in to any widely distributed codebase.

final

payload → List<int8_t>

Variable length payload. The length must be encoded in the payload as part of the message_type protocol, e.g. by including the length as payload data, or by terminating the payload data with a non-zero marker. This is required in order to reconstruct zero-terminated payloads that are (or otherwise would be) trimmed by MAVLink 2 empty-byte truncation. The entire content of the payload block is opaque unless you understand the encoding message_type. The particular encoding used can be extension specific and might not always be documented as part of the MAVLink specification.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

targetComponent → uint8_t

Component ID (0 for broadcast)

final

targetNetwork → uint8_t

Network ID (0 for broadcast)

final

targetSystem → uint8_t

System ID (0 for broadcast)

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

serialize() → ByteData

override

toString() → String

A string representation of this object.

Operators

The equality operator.
