Methods

extractData(RandomAccessSource src) → Future<Uint8List>
Extracts the data from the box.
getChildByTypePath(RandomAccessSource src, List<String> path, {bool isFullBoxCallback(String type)?}) → Future<ISOBox?>

Available on ISOBox, provided by the ISOBoxExtension extension

Returns a child box by a given type path. isFullBoxCallback is a callback to determine if a box is a full box.
getDirectChild(RandomAccessSource src, {bool isFullBoxCallback(String type)?, bool filter(ISOBox box)?}) → Future<ISOBox?>

Available on ISOBox, provided by the ISOBoxExtension extension

Return a direct child box by a given async filter. filter is a callback to filter boxes. isFullBoxCallback is a callback to determine if a box is a full box.
getDirectChildByAsyncFilter(RandomAccessSource src, Future<bool> filter(ISOBox box), {bool isFullBoxCallback(String type)?}) → Future<ISOBox?>

Available on ISOBox, provided by the ISOBoxExtension extension

Return a direct child box by a given async filter. filter is a callback to filter boxes. isFullBoxCallback is a callback to determine if a box is a full box.
getDirectChildByTypes(RandomAccessSource src, Set<String> types, {bool isFullBoxCallback(String type)?}) → Future<ISOBox?>

Available on ISOBox, provided by the ISOBoxExtension extension

Returns a direct child box by given types. An empty types set will return the first child box. isFullBoxCallback is a callback to determine if a box is a full box.
getDirectChildren(RandomAccessSource src, {bool isFullBoxCallback(String type)?, bool filter(ISOBox box)?}) → Future<List<ISOBox>>

Available on ISOBox, provided by the ISOBoxExtension extension

Return a list of direct children boxes by a given filter. filter is a callback to filter boxes. isFullBoxCallback is a callback to determine if a box is a full box.
getDirectChildrenByAsyncFilter(RandomAccessSource src, Future<bool> filter(ISOBox box), {bool isFullBoxCallback(String type)?}) → Future<List<ISOBox>>

Available on ISOBox, provided by the ISOBoxExtension extension

Return a list of direct children boxes by a given async filter. isFullBoxCallback is a callback to determine if a box is a full box.
getDirectChildrenByTypes(RandomAccessSource src, Set<String> types, {bool isFullBoxCallback(String type)?}) → Future<List<ISOBox>>

Available on ISOBox, provided by the ISOBoxExtension extension

Returns a list of direct children by given types. An empty types set will return all child boxes. isFullBoxCallback is a callback to determine if a box is a full box.
getFullBoxInfo() → ISOFullBoxInfo?
Returns the full box info.
nextChild(RandomAccessSource src, {bool isFullBoxCallback(String type)?, int? index, int skipOffset = 0}) → Future<ISOBox?>
Returns the next child box. If this box is not a container, returns null. src is the source to read from. isFullBoxCallback is a callback to determine if a box is a full box. index is an optional index to set on the returned box. skipOffset is an optional offset to skip before reading the next child box.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
parseFtyp(RandomAccessSource src) → Future<ISOBoxFtypData?>

Available on ISOBox, provided by the ISOBoxFtypExtension extension

resetPosition(RandomAccessSource src) → Future<void>
This calls seekInContent with an offset of 0, effectively resetting the position to the start of the box data.
seekInContent(RandomAccessSource src, int offset) → Future<void>
Sets the internal file position to the specified offset within the content of the box.
toBytes(RandomAccessSource src) → Future<Uint8List>
Returns the box as bytes. This includes the header and the data.
toDict() → Map<String, dynamic>
Converts the box to a dictionary.
toString() → String
A string representation of this object.
override

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Static Methods

createRootBox() → ISOBox
Creates a root ISOBox.
