Send large text as input

I want to send a large input to my app. Iam using sendKeys()
If I use sendKeys it types every key which takes lot of time for sending the text.
Can anyone please suggest some way to send whole content at a time rather than typing each and every key so that it saves lot of time.

Thanks in advance

Is this field web element or native?

You can try sending the data by command line execution.

adb shell input text "YourText"

I’m not sure how fast it can be but still it would be faster then the sendKeys().
Please do share the outcome if you try this.
