WEBVTT 00:00.120 --> 00:01.120 Welcome back. 00:01.160 --> 00:04.920 We added the clustering library dependency. 00:05.200 --> 00:08.000 Now let's move to the main activity. 00:08.000 --> 00:12.560 And here let's move to the Google map scope. 00:12.600 --> 00:16.000 Let's start by marker clustering. 00:16.240 --> 00:18.840 Start with clustering. 00:19.040 --> 00:26.480 And here we have this composable function I want from you to focus with me. 00:26.480 --> 00:32.200 Select Clustering Ctrl and left click to open the declaration. 00:32.480 --> 00:36.440 And here we can notice that it's a public function. 00:36.440 --> 00:47.080 Clustering takes whatever any collection of that extends from cluster item and items collection T. 00:47.240 --> 00:55.800 This is very important because we're going to see what what uh what is the problem with this library 00:55.800 --> 00:59.160 and why we should pay attention to this declaration. 00:59.160 --> 01:05.580 And we have a lot of things we can, uh, declare on marker. 01:05.580 --> 01:07.020 Click on info window. 01:07.020 --> 01:08.980 Click on marker. 01:08.980 --> 01:10.260 Drag on info window. 01:10.860 --> 01:11.940 Click marker. 01:11.940 --> 01:15.100 Drag end and marker drag start okay. 01:15.300 --> 01:20.740 Also, we can see a lot of things inside this composable function. 01:20.740 --> 01:24.060 Also, we can notice that we have the cluster. 01:24.100 --> 01:29.860 Another version of the clustering items collection of T on cluster. 01:29.860 --> 01:32.140 Click we can handle on cluster. 01:32.140 --> 01:35.140 Click also on cluster item click. 01:35.180 --> 01:41.860 You can also define if the user clicks on the marker inside the cluster, or the user clicks on the 01:41.860 --> 01:43.180 cluster in general. 01:43.380 --> 01:53.940 Also, if the user clicks on the info window of the cluster item, also click Cluster Content, Cluster 01:53.940 --> 01:57.020 Item Content and on Cluster Manager. 01:57.020 --> 02:00.500 So we need this version of clustering. 02:00.500 --> 02:11.520 So back to here you can remove clustering and you can select here from those three cluster items from 02:11.560 --> 02:12.560 the clustering. 02:12.720 --> 02:21.200 So clustering you should specify some mandatory parameters like the items equals to. 02:21.640 --> 02:28.600 And here we need to specify the list of markers that we need to make a cluster. 02:28.640 --> 02:29.200 Okay. 02:29.520 --> 02:35.520 So I want from you to pay attention with me now because there is a very important note. 02:35.520 --> 02:37.480 You should pay attention to it. 02:37.520 --> 02:38.000 Okay. 02:38.160 --> 02:42.000 Let me create a list of markers. 02:42.000 --> 02:51.640 So here outside the Google map let me create the variables for the clustering example list of and here 02:51.800 --> 02:58.640 we need to for example make a marker list of markers and or. 02:58.680 --> 02:59.400 Let long. 02:59.440 --> 03:02.000 Let me start with lat long set. 03:02.040 --> 03:07.600 For example the first lat long at the equator zero zero. 03:07.800 --> 03:10.960 The second one is near it okay. 03:11.120 --> 03:16.380 So this this is the cluster items as of list of lat long. 03:16.420 --> 03:25.180 Now let's scroll down to clustering inside the Google Maps and let's specify the cluster items here. 03:25.340 --> 03:29.820 There is a very important note you should pay attention to it. 03:29.860 --> 03:34.700 Required cluster item but found lat long. 03:35.020 --> 03:42.300 If we create any type of lists it will give us this type of error. 03:42.460 --> 03:43.780 Type mismatch. 03:43.780 --> 03:44.500 Required. 03:44.500 --> 03:46.540 Cluster item found. 03:46.580 --> 03:47.860 Lat long. 03:48.100 --> 03:50.740 So let's go back to the cluster items. 03:50.740 --> 03:53.100 And here it's list of lat long. 03:53.140 --> 03:56.340 Let me try list of markers for example. 03:56.380 --> 03:56.860 Okay. 03:57.180 --> 04:00.860 Also we will get the same error. 04:01.140 --> 04:05.020 It's of type marker required cluster item. 04:05.340 --> 04:06.540 How to solve it. 04:06.580 --> 04:13.020 In the next video, we're going to create the cluster item that extends from cluster item. 04:13.020 --> 04:19.420 And we're going to create the custom items to be displayed for the clusters.
