title: Is there currently any way to center the hint of a multi-line TextField?
body: <p>I have a TextField that can hold multi-line input, pretty much simulating a TextArea since flutter doesn't have those.</p>
  <p>The problem I'm encountering is that the hint text isn't vertically centered, even though the prefixIcon is.</p>
  <pre class="lang-dart prettyprint-override"><code>Container(
          padding: EdgeInsets.only(right: displayWidth(context) * 0.05),
          alignment: Alignment.centerLeft,
          height: displayHeight(context) * 0.28,
          width: displayWidth(context) * 0.75,
          decoration: roundedShadowDecoration(context: context, color: secondaryRed(), size: 0.015),
          child: TextField(
            maxLines: 7,
            cursorColor: Colors.white,
            style: GoogleFonts.notoSans(
                color: Colors.white, fontSize: displayWidth(context) * 0.04),
            decoration: InputDecoration(
              border: InputBorder.none,
              prefixIcon: Icon(
                Icons.font_download,
                color: Colors.white,
                size: displayWidth(context) * 0.065,
              ),
              hintText: &quot;A TextField Hint&quot;,
              hintStyle: GoogleFonts.notoSans(
                  color: Colors.white54, fontSize: displayWidth(context) * 0.035),
            ),
          ),
        ),
  </code></pre>
