Methods

addOnPointAnnotationClickListener(OnPointAnnotationClickListener listener) → void
Add a listener to receive the callback when an annotation is clicked.
create(PointAnnotationOptions annotation) → Future<PointAnnotation>
Create a new annotation with the option.
createMulti(List<PointAnnotationOptions> annotations) → Future<List<PointAnnotation?>>
Create multi annotations with the options.
delete(PointAnnotation annotation) → Future<void>
Delete an added annotation.
deleteAll() → Future<void>
Delete all the annotation added by this manager.
getIconAllowOverlap() → Future<bool?>
If true, the icon will be visible even if it collides with other previously drawn symbols.
getIconIgnorePlacement() → Future<bool?>
If true, other symbols can be visible even if they collide with the icon.
getIconKeepUpright() → Future<bool?>
If true, the icon may be flipped to prevent it from being rendered upside-down.
getIconOptional() → Future<bool?>
If true, text will display without their corresponding icons when the icon collides with other symbols and the text does not.
getIconPadding() → Future<double?>
Size of the additional area around the icon bounding box used for detecting symbol collisions.
getIconPitchAlignment() → Future<IconPitchAlignment?>
Orientation of icon when map is pitched.
getIconRotationAlignment() → Future<IconRotationAlignment?>
In combination with symbol-placement, determines the rotation behavior of icons.
getIconTextFit() → Future<IconTextFit?>
Scales the icon to fit around the associated text.
getIconTextFitPadding() → Future<List<double?>?>
Size of the additional area added to dimensions determined by icon-text-fit, in clockwise order: top, right, bottom, left.
getIconTranslate() → Future<List<double?>?>
Distance that the icon's anchor is moved from its original placement. Positive values indicate right and down, while negative values indicate left and up.
getIconTranslateAnchor() → Future<IconTranslateAnchor?>
Controls the frame of reference for icon-translate.
getSymbolAvoidEdges() → Future<bool?>
If true, the symbols will not cross tile edges to avoid mutual collisions. Recommended in layers that don't have enough padding in the vector tile to prevent collisions, or if it is a point symbol layer placed after a line symbol layer. When using a client that supports global collision detection, like Mapbox GL JS version 0.42.0 or greater, enabling this property is not needed to prevent clipped labels at tile boundaries.
getSymbolPlacement() → Future<SymbolPlacement?>
Label placement relative to its geometry.
getSymbolSpacing() → Future<double?>
Distance between two symbol anchors.
getSymbolZOrder() → Future<SymbolZOrder?>
Determines whether overlapping symbols in the same layer are rendered in the order that they appear in the data source or by their y-position relative to the viewport. To control the order and prioritization of symbols otherwise, use symbol-sort-key.
getTextAllowOverlap() → Future<bool?>
If true, the text will be visible even if it collides with other previously drawn symbols.
getTextFont() → Future<List<String?>?>
Font stack to use for displaying text.
getTextIgnorePlacement() → Future<bool?>
If true, other symbols can be visible even if they collide with the text.
getTextKeepUpright() → Future<bool?>
If true, the text may be flipped vertically to prevent it from being rendered upside-down.
getTextLineHeight() → Future<double?>
Text leading value for multi-line text.
getTextMaxAngle() → Future<double?>
Maximum angle change between adjacent characters.
getTextOptional() → Future<bool?>
If true, icons will display without their corresponding text when the text collides with other symbols and the icon does not.
getTextPadding() → Future<double?>
Size of the additional area around the text bounding box used for detecting symbol collisions.
getTextPitchAlignment() → Future<TextPitchAlignment?>
Orientation of text when map is pitched.
getTextRotationAlignment() → Future<TextRotationAlignment?>
In combination with symbol-placement, determines the rotation behavior of the individual glyphs forming the text.
getTextTranslate() → Future<List<double?>?>
Distance that the text's anchor is moved from its original placement. Positive values indicate right and down, while negative values indicate left and up.
getTextTranslateAnchor() → Future<TextTranslateAnchor?>
Controls the frame of reference for text-translate.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
