WEBVTT 00:00.080 --> 00:06.800 Welcome back for the first features like the model year, acceleration, weight, horsepower, displacement, 00:06.800 --> 00:07.720 cylinders. 00:07.800 --> 00:14.160 We specified a text fields and allow the user to enter data inside the text fields. 00:14.200 --> 00:19.440 Now we're going to make for the origin parameter. 00:19.440 --> 00:26.160 For the origin feature, we're going to allow the user to select one of the buttons. 00:26.160 --> 00:31.560 One of the origins European American Japanese. 00:31.880 --> 00:38.000 So we're going to allow the user to select only one button from the group. 00:38.280 --> 00:44.520 So for that create a new Kotlin file inside the screens package. 00:44.560 --> 00:47.240 Name it as origin chip. 00:47.400 --> 00:56.480 So we're going to create a chip composable function text a string selected boolean and on click lambda 00:56.480 --> 00:57.880 expression okay. 00:58.040 --> 01:01.440 Start with filter chip. 01:01.720 --> 01:10.400 Set the selected to selected on click to unclick and the label a new text with with the parameter text 01:10.400 --> 01:18.300 that it's best filter chip is a Material Design component in Jetpack Compose that allows users to select 01:18.300 --> 01:20.940 multiple options from a set. 01:21.100 --> 01:24.340 It's commonly used for filtering and categorizing. 01:24.500 --> 01:33.420 Okay, so we're going to use it for selecting the origin of the car back to our car features form. 01:33.420 --> 01:37.380 Under this text create a new row. 01:37.620 --> 01:48.580 Set the modifier to modifier dot fill maximum width horizontal arrangement space evenly alt plus enter 01:48.580 --> 02:00.140 to add this arrangement dot space evenly and here inside this row, start creating the first origin 02:00.300 --> 02:00.980 chip. 02:01.140 --> 02:03.940 Set the text for American selected. 02:04.140 --> 02:11.820 Set the car origin to one F and on click on features changed car features dot copy. 02:12.100 --> 02:17.420 We need to convert to this form, so please pay attention to me. 02:17.580 --> 02:25.570 The first chip, the origin chip named as American set the selected The car features one equals to one 02:25.610 --> 02:25.930 f. 02:25.970 --> 02:27.450 Back to car features. 02:27.450 --> 02:31.570 Here we need to set the origin 1 to 1 f. 02:31.690 --> 02:38.370 But the problem here that our model needs only one origin. 02:38.570 --> 02:41.330 We need to pass only one origin. 02:41.330 --> 02:49.170 And the value for the origin one is one, American one, European two, and Japanese three. 02:49.210 --> 02:57.170 To solve this problem, we need to set the other ones the other origins to zeros. 02:57.170 --> 03:04.610 So here this is what we've did since it's American and it's uh it's number is one. 03:04.610 --> 03:08.410 So here we set the origin one equals to one which is true. 03:08.450 --> 03:13.610 The origin two is false and origin three is false or zero okay. 03:13.850 --> 03:18.170 So this is how we specify the American origin. 03:18.410 --> 03:21.210 The similar to what we've done here. 03:21.450 --> 03:30.570 Let me copy this origin and paste it to here and change the American to European set. 03:30.570 --> 03:41.590 The car features origin to to 1 F and the origin here set it to zero, the origin 2 to 1 and origin 03:41.590 --> 03:43.510 three equals to zero. 03:43.590 --> 03:50.590 Similar to this, we're going to copy the European and paste it here for the Japanese. 03:50.590 --> 03:52.630 So we have American. 03:52.630 --> 03:54.030 We have European. 03:54.030 --> 03:59.950 And now Japanese set the origin to three equals to one. 04:00.430 --> 04:07.710 And set the origin to to zero and make the origin three equals to one f okay. 04:07.830 --> 04:11.030 So this is our origin chips. 04:11.030 --> 04:16.870 Now let's call this function and run our application to see the results. 04:16.870 --> 04:18.550 So car features four. 04:18.710 --> 04:25.670 Copy this and let's go to Car Mileage Predictor inside the input form. 04:25.670 --> 04:28.550 Let me call this composable. 04:28.550 --> 04:37.590 And we need we need to pass the parameters the car features or features chains and validation errors. 04:37.590 --> 04:41.830 In the next video we're going to create those variables and run our application.
