Modals can be created using a [Modal Controller](../../modal-controller/ModalController). They can be customized by passing modal options in the modal controller's create method.
### Passing paramaters
When a modal is created, paramaters might be passed to the newly created modal:
```ts
// Create a modal using MyModalComponent with some initial data
const modal = await modalController.create({
component: MyModalComponent,
componentProps: {
'prop1': value,
'prop2': value2
}
});
```
Under the hood, the controller creates a new `ion-modal` and attaches the specified component to it.
It also assigns the specified `componentProps` to the component's instance:
```js
// pseudo-code
const instance = create(MyModalComponent);
instance.prop1 = value;
instance.prop2 = value2;
```
This way, your component can access the passed params, check the "Usage" section for further code example for each frameworks.
### Retuning data
Modals can also return data back to the controller when they are dismissed.
```js
const modal = await modalController.create({...});
const { data } = await modal.onDidDismiss();
console.log(data);
```
```js
// Dismiss the top modal returning some data object
modalController.dismiss({
'result': value
})
```
