}) export class HomePage {

fileforSending ; fileUri :string; filePath :string; fileName :string; fileType :string; buffer ; entry;

choose(){ this.fileChooser.open() .then(uri => { //getting URI of a choosen file this.fileUri = uri; return this.file.resolveLocalFilesystemUrl(this.fileUri);

}).then(fileEntry => {
  this.entry = fileEntry;
  this.entry.file((arg) => {
  //getting mime type of a file
  this.fileType = arg.type;})

}).then(() => {
  return this.pathConverter.resolveNativePath(this.fileUri)

}).then((filePath) => {
  //converting file URI to normal file PATH & file NAME
  this.filePath = filePath.substring(0, filePath.lastIndexOf('/'));
  this.fileName = filePath.substring(filePath.lastIndexOf('/'), filePath.length).replace("/", "");
  
}).then(async () => {
  return await this.file.readAsArrayBuffer(this.filePath, this.fileName)
}).then(async (file) => {
    //getting file 
    await this.fireService.uploadFileToStorage(file, this.fileType, this.fileName);
})
.catch(err =>  {
    console.log('error: ', err)
});

} } `

    console.log(oMyBlob)
    const uploadTask = this.af.upload(
