<StackLayout>
    <Label text="Enter the station name:"></Label>
    <TextField hint="Station name" col="0" [ngModel]="stationName" (ngModelChange)="stationTyping($event)"></TextField>

Answer №1

ENOSPC === no space left on device

Encountering this error is common when using emulators with limited storage capacity, such as the default 200MB. If you have installed multiple applications, especially those in debug mode that consume more space than release versions, you may run out of space for testing. To resolve this issue, either increase the storage capacity of your emulator or uninstall some applications to free up space.

Answer №2

Hey there! Below is an example of how I am utilizing an event listener to capture the input value.

//Example usage...
<TextField 
        #revqrt
        [(ngModel)]="fd_recqty" 
        keyboardType="number">
</TextField>

//Typescript file

...
import { fromEvent } from 'rxjs';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/debounceTime';
...

ngAfterViewInit(): void {
 this.$qtyListener= fromEvent(
     this.receiptQty.nativeElement, 'textChange')
     .debounceTime(400)
     .subscribe((event:any) => {
        console.log(event.value); // This logs the input value
  });
}
