@stuartmorgan Could you please label this issue? Thank you for your effort!

urmilshroff commented 4 years ago

Any word on this issue? I'm also looking for a way to display density hotspots/heatmaps in my Flutter app with the Maps plugin.

jerfeson commented 4 years ago

I am looking forward to this feature.+1

DCubix commented 4 years ago

I needed this feature asap!

clemclx commented 4 years ago

Agree ! Would really appreciate heatmap layer support..

fvisticot commented 4 years ago

Mandatory for our app. Please add this feature

MpEliaz commented 4 years ago

Please add!

SvenSlijkoord commented 4 years ago

Heatmap support is implemented for both Android & iOS in PR flutter/plugins#2454 but I am having trouble getting the podspec file to build because Google-Maps-iOS-Utils is a static framework dependency.

The build_all_plugins_ipa task gives the following error:

[!] The 'Pods-Runner' target has transitive dependencies that include statically linked binaries

Does anyone know how to include the Google-Maps-iOS-Utils dependency without breaking the build?

cyanglaz commented 4 years ago

After looking into the google-maps-utils repo, I want to experiment to have a separate flutter plugin to handle all the features in the google-maps-utils. I will set up the new plugin and add some minimum code. After that, we can work together to add these new features. Including heat-map mentioned in this issue.

+1 this would be a brilliant thing to have accessible in Flutter

+1, looking forward to having full heatmap support in Flutter!

I urgently needed this feature so i have forked the pull request And published a forked package google_maps_flutter_heatmap (Tested only on android)

rouvoy commented 4 years ago

Thanks for the fork and the package release, but it only seems to work on Android, unfortunately.

arok commented 4 years ago

@rouvoy see my fork https://github.com/arok/plugins/tree/implement_google_maps_flutter_heatmap it also works on iOS

mlemos commented 4 years ago

Please add this feature. This is a must-have for lots of maps based applications.

Where you able to find a way to implement heat maps in flutter?

Rexios80 commented 2 years ago

Working on this in https://github.com/flutter/plugins/pull/5274. I have tested basic heatmap support on Android and web. iOS and more testing needs done.

Rexios80 commented 2 years ago

iOS implementation is working now too

Rexios80 commented 1 year ago

Did you pass a heatmap with no points?

wH1t3-l0tUs commented 1 year ago

Yes I fixed it, the map was created before the data had come

Rexios80 commented 1 year ago

I should probably add an assertion that the heatmap data isn't empty

wH1t3-l0tUs commented 1 year ago

@Rexios80 is there any way to control the camera of the heatmap? I want to change the position of it, but the googlemapcontroller is not able to use in it.

Rexios80 commented 1 year ago

Yeah it is

wH1t3-l0tUs commented 1 year ago

@Rexios80 can you show it? I have to recreate the map to init the camera position again

Rexios80 commented 1 year ago

The heatmap is just a layer. Everything else works exactly the same as without heatmaps.

wH1t3-l0tUs commented 1 year ago

@Rexios80 Is there any way to keep the color of the layer when we zoom in? As I zoom out, the color of each point is correct, but when zooming in, the points combine together, but their color is change to the max intensity

SuhasGaidhane commented 8 months ago

anyone have working project to Show HeatMap on FlutterApp Please provide Github Link

Rexios80 commented 8 months ago

The example app in my fork has a heatmap implementation

This issue is marked P1 but has had no recent status updates.

The P1 label indicates high-priority issues that are at the top of the work list. This is the highest priority level a bug can have if it isn't affecting a top-tier customer or breaking the build. Bugs marked P1 are generally actively being worked on unless the assignee is dealing with a P0 bug (or another P1 bug). Issues at this level should be resolved in a matter of months and should have monthly updates on GitHub.

Please consider where this bug really falls in our current priorities, and label it or assign it accordingly. This allows people to have a clearer picture of what work is actually planned. Thanks!

This is in progress; keeping P1.
