# google_map_polyutil
Dart bridge between native google map utility class PolyUtil and your application.
Now you can use all PolyUtil methods that are available in google map utility class PolyUtil.
# Usage
Import `package:google_map_polyutil/google_map_polyutil.dart` and then you are all set to call all it's static methods.
# Methods available
* `containsLocation` [Future] : Computes whether the given point lies inside the specified polygon.
* `decode` [Future>] : Decodes an encoded path string into a sequence of LatLngs.
* `distanceToLine` [Future] : Computes the distance on the sphere between the point p and the line segment start to end.
* `encode` [Future] : Encodes a sequence of LatLngs into an encoded path string.
* `isClosedPolygon` [Future] : Returns true if the provided list of points is a closed polygon (i.e., the first and last points are the same), and false if it is not.
* `isLocationOnEdge` [Future] : Computes whether the given point lies on or near the edge of a polygon, within a specified tolerance in meters.
* `isLocationOnPath` [Future] : Computes whether the given point lies on or near a polyline, within a specified tolerance in meters.
* `simplify` Future> : Simplifies the given poly (polyline or polygon) using the Douglas-Peucker decimation algorithm.
# Example
```dart
// Let's prepare dummy arguments.
List paths = [];
paths.add(LatLng(0,0));
paths.add(LatLng(0,1));
paths.add(LatLng(0,2));
paths.add(LatLng(0,4));
// Coordinate you want to check if it lies within or near path.
LatLng point = LatLng(0, 3);
String encodedString = "???_ibE?_seK?_ibE";
```
### containsLocation
```dart
GoogleMapPolyUtil.containsLocation(
point: point,
polygon: paths
).then((result) => print(result));
```
### decode
```dart
GoogleMapPolyUtil.decode(
encodedPath: encodedPath
).then((result) => print(result));
```
### distanceToLine
```dart
GoogleMapPolyUtil.distanceToLine(
point: LatLng(0, 0),
start: LatLng(0, 0),
end: LatLng(0, 8)
).then((result) => print(result));
```
### encode
```
GoogleMapPolyUtil.encode(
path: paths
).then((result) => print(result));
```
### isClosedPolygon
```dart
GoogleMapPolyUtil.isClosedPolygon(
poly: path,
polygon: paths
).then((result) => print(result));
```
### isLocationOnEdge
```
GoogleMapPolyUtil.isLocationOnEdge(
point: point,
polygon: paths
).then((result) => print(result));
```
### isLocationOnPath
```dart
GoogleMapPolyUtil.isLocationOnEdge(
point: point,
polygon: paths
).then((result) => print(result));
```
### simplify
```dart
GoogleMapPolyUtil.simplify(
poly: paths,
tolerance: 100
).then((result) => print(result));
```
